title: 10,12-Dimethyl-pteridino[6,7-f][1,10]phenanthroline-11,13(10H,12H)-dione-chloro-form (1/1).
abstract: In the title co-crystal, C(18)H(12)N(6)O(2)·CHCl(3), intra-molecular Cl(3)C-H⋯N hydrogen-bonding inter-actions occur between a single CHCl(3) and both N atoms at the 1,10-positions on the phenanthroline portion of the mol-ecule. The inter-planar distance between inversion-related mol-ecules is 3.241 (2) Å.
