Bulletin of the Academy of Sciences of the USSR, Division of Chemical Science
6-Amino-2-(p-aminophenyl)-4-phenylquinazoline (I), a monomer for the preparation of polymers, has been synthesized and studied by x-ray diffraction. The basic geometric characteristics of the molecule of compound (I) have been established-the small angle between the vectors along the C-NH2 bonds [3.0 and 5.7° in the two symmetrically independent molecules (Ia) and (Ib), with distance between the N atoms of the amino groups 11.908 and 11.767(3) Å] and the coplanarity of the p-aminophenyl ring and the quinazoline rings (dihedral angle 1.0 and 3.3°)- and together with available data indicate the possibility of obtaining rigid-chain polymers based on compound (I).
