The crystal structure of pirfenidone, C12H11NO [alternative name: 5-methyl-1-phenyl­pyridin-2(1H)-one], an active pharmaceutical ingredient (API) approved in Europe and Japan for the treatment of Idiopathic pulmonary fibrosis (IPF), is reported here for the first time. It was crystallized from toluene by the temperature gradient technique, and crystallizes in the chiral monoclinic space group P21. The phenyl and pyridone rings are inclined to each other by 50.30 (11)°. In the crystal, mol­ecules are linked by C–H⋯O hydrogen bonds involving the same acceptor atom, forming undulating layers lying parallel to the ab plane.

The crystal structure of the organic pigment 2-monomethyl-quinacridone (Pigment Red 192, C21H14N2O2) was solved from X-ray powder diffraction data. The resulting average structure is described in space group Poverline 1, Z = 1 with the molecule on the inversion centre. The molecules are arranged in chains. The molecules, which have no inversion symmetry, show orientational head-to-tail disorder. In the average structure, the methyl group is disordered and found on both ends of the molecule with an occupancy of 0.5 each. The disorder and the local structure were investigated using various ordered structural models. All models were analysed by three approaches: Rietveld refinement, structure refinement to the pair distribution function (PDF) and lattice-energy minimization. All refinements converged well. The Rietveld refinement provided the average structure and gave no indication of a long-range ordering. The refinement to the PDF turned out to be very sensitive to small structural details, giving insight into the local structure. The lattice-energy minimizations revealed a significantly preferred local ordering of neighbouring molecules along the [0ar 11] direction. In conclusion, all methods indicate a statistical orientational disorder with a preferred parallel orientation of molecules in one direction. Additionally, electron diffraction revealed twinning and faint diffuse scattering.

The crystal structure of the nanocrystalline pigment mono­methyl-quinacridone was solved from X-ray powder data. The orientational disorder was investigated using Rietveld refinements, structure refinement to the pair-distribution function, and lattice-energy minimizations of various ordered structural models.

"Live! Life's a banquet and most poor suckers are starving to death!" - Auntie Mame.

Your calendar is filling up, but here are four holiday events you'll want to make room for:

Every year, pioneering Chicano artist Frank Romero and his wife Sharon throw a big studio sale that includes works by a wide group of artists, and a lot of food and drink. It's just as much a party as a sales event, and Frank and the other artists are always there to meet and greet. And now that the couple is spending more time at their home in France, it's a chance for their old friends to catch up with them, so who knows who you'll see from L.A.'s arts community.

The Romero Studio annual Christmas party and sale is Saturday, Dec. 6, 6-10pm; and Sunday, Dec. 7, 1-5pm, at Plaza de la Raza, Boathouse Gallery, 3540 North Mission Rd., LA CA 90031 (in Lincoln Park across from the DMV — which BTW is a very good DMV).

Then, on Sunday, Dec. 14, at 4:30pm,  it's the Advent Procession of Lessons and Carols, at St. James Episcopal Church, which a friend describes as "one of the truly beautiful choral events of the season," and the highlight of the Choir of St. James' season. It's free and it's at St. James' Episcopal Church in Koreatown (3903 Wilshire Blvd., Los Angeles 90010).
 

"Auntie Mame," the 1958 Rosalind Russell movie with more quotable quips than a weekend getaway with Oscar Wilde, has become something of a Christmas tradition. It's screening at the American Cinematheque's Egyptian Theatre on Wednesday, Dec. 17, at 7:30. As delightful as this movie is any day of the week on your TV at home, this is a film to be seen in 35mm with a theater full of people reacting to every bon mot and heart-touching moment.

GO INSIDE: The Disney Hall organ, "Hurricane Mama," turns 10

Last year, my husband and I blindly went to Disney Hall for the Holiday Organ Spectacular. We expected some music and a little fun. But it really was spectacular. It's back this year, on Friday, Dec. 19, with organist David Higgs leading the evening from the console of Hurricane Mama.

If you've never seen or heard the organ in person, this is a great evening because Higgs — a teacher as well as master organist — gives you a guided tour of every stop, and every mood the organ can produce, from cathedral-loud to country-church-quiet. At the end of the night, he breaks the audience into parts to sing "The Twelve Days of Christmas," and you may sing as loud as you like.

These are just a few curated selections, but they're just the tip of the iceberg in Southern California; please make your own holiday event recommendations in the comments below.

Now that the holiday season is winding down, thrift shops run by Goodwill, the Salvation Army, and other organizations are tallying up the annual flood of December donations. 

"It's always been a tradition that our donors donate between Christmas and New Year's ... and the last couple days of the year, they donate even more," Goodwill Southern California director of logistics Tinna Bauer explained. "Some do it for tax purposes, and some ... when they if they receive new items for Christmas, they clean out the old."

If you want a job in Los Angeles County, you’re best off being a nurse or a hotel worker and you’re less likely to find employment in manufacturing. 

We’re getting our first look at the employment numbers for 2014, which show mostly good news: California’s unemployment has fallen to 7 percent, the lowest rate in five and a half years. (The final numbers come out in March)

The state’s job growth outpaced the rest of the country for the third straight year, though it slowed slightly towards the end of the year.

California added jobs at a 2.2 percent annual rate last year, outpacing the nation’s 1.8 percent rate. 

Los Angeles County fared the worst as far as seasonally adjusted year-to-year job gains among California's major metropolitan areas, according to The Los Angeles County Economic Development Corp.:

• San Jose/Silicon Valley +4 percent
• San Francisco Bay Area + 3.8 percent 
• San Diego +3.3 percent
• Inland Empire +1.9 percent
• Orange County +2.3 percent
• Ventura +2 percent
• Los Angeles +1.7 percent

Los Angeles County's unemployment rate is 7.9 percent, down from 9.2 percent a year ago, and once again it was health care that added the most jobs: 22,000.

"Part of it is demographic, and part of it was the Affordable Care Act, which is helping more individuals take advantage of health care," said Robert Kleinhenz, Chief Economist at the L.A. County Economic Development Corp.

Aside from an aging population needing more health care, Kleinhenz adds that more people can afford to get medical treatment because of the improvement in the economy. 

With more money in their pockets, more people have also been traveling, which made leisure and hospitality the second-best area for job growth in the county, with 11,300 new jobs.

What's not doing well? 

Manufacturing, especially in non-durable goods – which includes food and clothing – lost the most jobs in L.A. County in 2014: 6,700 jobs. The only other sector that shed jobs was the government, which lost almost 3,800 jobs positions last year.

Kleinhenz also pointed to wholesale trade, which lost 300 jobs year-to-year in but saw job growth in the Inland Empire. 

"Some parts of the goods movement may be moving into the Inland Empire, where we have seen in recent years quite a bit of warehouse building taking place,” said Kleinhenz.
