7-(4-Methoxy-phen-yl)-5-methyl-9-phenyl-7H-pyrrolo[2',3':4,5]pyrimido[1,6-d]tetrazole.

ABSTRACT: The title compound, C(20)H(16)N(6)O, is composed of a tetra-zolo ring and a 4-methoxy-phenyl and a benzene-substituted pyrrole ring at the 7 and 9 positions fused to a pyrimidine ring in a nearly planar fashion [maximum deviation of 0.018 (1) Å for the fused ring system]. A methyl group at the 5 position is also in the plane of the hetero cyclic system. The dihedral angle between the mean planes of the benzene and 4-methoxy-phenyl rings is 40.4 (2)°. The dihedral angles between the mean planes of the pyrimidine and the benzene and 4-methoxy-phenyl rings are 15.6 (5)° and 52.6 (7)°, respectively. A weak intra-molecular C-H⋯N hydrogen bond inter-action, which forms an S(7) graph-set motif, helps to establish the relative conformations of the tetrazolo and benzene rings. In the crystal, weak
