10,12-Dimethylpteridino[6,7-f][1,10]phenanthroline-11,13(10H,12H)-dione–chloroform (1/1)

Abstract

Key indicators: single-crystal X-ray study; T = 173 K; mean (C-C) = 0.002 Å; R factor = 0.032; wR factor = 0.095; data-to-parameter ratio = 12.3.In the title co-crystal, C 18 H 12 N 6 O 2 ÁCHCl 3 , intramolecular Cl 3 C-HÁ Á ÁN hydrogen-bonding interactions occur between a single CHCl 3 and both N atoms at the 1,10-positions on the phenanthroline portion of the molecule. The interplanar distance between inversion-related molecules is 3.241 (2) Å . Table 1 Hydrogen-bond geometry (Å , ).
