Abstract
Crystalline 4-nitro-1-phenylimidazole, C9H7N3O2, (I), and 4'-nitro-1-phenyl-4,1'-biiimidazole, C12H9N5O2, (II), contain C-H...O and C-H...N hydrogen bonds, connecting the molecules into infinite chains. The aromatic fragments in both compounds are nearly planar. The dihedral angles between the benzene and imidazole rings are 26.78 (5) degrees in (I) and 29.36 (8) degrees in (II).Entities:
