Chlordiazepoxide dichloro-methane monosolvate.

7-chloro-2-methyl-amino-5-phenyl-3H-1,4-benzodiazepine 4-oxide dichloro-meth-ane monosolvate), C(16)H(14)ClN(3)O·CH(2)Cl(2), the seven-membered ring adopts a boat conformation with the CH(2) group as the prow and the two aromatic C atoms as the stern. The dihedral angle between the benzene rings is 75.25 (6)°. The crystal structure features centrosymmetric pairs of chlordiazepoxide mol-ecules linked by pairs of N-H⋯O hydrogen bonds, which generate R(2) (2)(12) loops.
