摘要：

The title compound 2-benzylamino-6-methyl-3-cyano-8-phenyl-5H-bispyrazolo[3,4-d,3',2'-b]pyrimidine crystallizes in orthorhombic, space group Pbca with a = 17.945(7), b = 10.862(4), c = 19.481(7) angstrom, beta = 90 degrees, Z = 8, V = 1151.8(4) angstrom(3), M-r = 379.43, D-x = 1.327 g/cm(3), mu(MoK alpha) = 0.084 mm(-1), F(000) = 1584, the final R = 0:0513 and wR = 0.1128 for 2608 observed reflections (I > 2 sigma(I)). X-ray analysis reveals that the tricyclic portion of the molecule is effectively planar. In addition, there exist three intermolecular hydrogen bonds.
