Crystal structure of 5,7-diphenyl-4,7-dihydrotetrazolo[1,5-a]pyrimidine

Abstract

In the title molecule, C16H13N5, the plane of the tetrazole ring forms dihedral angles of 16.37 (7) and 76.59 (7)° with the two phenyl rings. The dihedral angle between the phenyl rings is 68.05 (6)°. The pyrimidine ring is in a flattened boat conformation. In the crystal, molecules are linked by pairs of N—H...N hydrogen bonds, forming inversion dimers.
