2-Amino-5-oxo-4-(thio­phen-2-yl)-5,6,7,8-tetra­hydro-4H-chromene-3-carbo­nitrile

In the crystal structure of the title compound, inter­molecular N—H⋯N and N—H⋯O hydrogen bonds form a two-dimensional supra­molecular network along the ac plane, contributing to the cohesion of the crystal.

Structural insights into 1,4-bis­(neopent­yloxy)pillar[5]arene and the pyridine host–guest system

The crystal structure of a neo­pentyl­oxypillar[5]arene with two pyridine mol­ecules encapsulated in the macrocyclic cavity is reported.

2,4-Di­chloro-6-{N-[2-(tri­fluoro­meth­yl)phen­yl]carboximido­yl}phenol

The title compound was synthesized by the condensation between tri­fluoro­methyl­aniline and di­chloro­salicyl­aldehyde by nucleophilic addition, forming a hemiaminal, followed by a dehydration to generate an imine. The compound crystallizes in an ortho­rhom­bic Pbca (Z = 8) space group with a dihedral angle of 44.70 (5)° between the two aromatic rings. In the crystal, the mol­ecules pack together to form a zigzag pattern along the c axis.
