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)(。A), β = 90°, Z = 8, V = 1151.8(4)(。A)3, Mr = 379.43, Dx = 1.327 g/cm3,μ(MoKα) = 0.084 mm 1, F(000) = 1584, the final R = 0.0513 and wR = 0.1128 for 2608 observed reflections (I ＞ 2σ(I)).X-ray analysis reveals that the tricyclic portion of the molecule is effectively planar.In addition, there exist three intermolecular hydrogen bonds.
