Relevant π-hole tetrel bonding interactions in ethyl 2-triazolyl-2-oxoacetate derivatives: Hirshfeld surface analysis and DFT calculations

CrystEngComm, 2020, Advance Article
DOI: 10.1039/D0CE00335B, Paper
Muhammad Naeem Ahmed, Khawaja Ansar Yasin, Shahid Aziz, Saba Urooge Khan, Muhammad Nawaz Tahir, Diego Mauricio Gil, Antonio Frontera
We report the synthesis and X-ray characterization of four triazole derivatives that include an α-ketoester functionality and two phenyl substituents. The compounds form self-assembled dimers in the solid state establishing two symmetrically equivalent O⋯π-hole interactions.
