摘　　要：The title compound (C22H32.5ClCoN6O8.25, Mr = 607.42) crystallizes in the orthor- hombic system, space group C2221 with a = 11.320(2), b = 20.933(4), c = 23.936(5) ? V = 5672(2) 3, Dc = 1.423 g/cm3, Z = 8, m(MoKa) = 0.754 mm-1, F(000) = 2532, R = 0.0512 and wR = 0.1190. There are eight complex molecules [Co(C4H6N2O2)(C4H8N2O2)(C7H9N)2]ClO40.25H2O of C2 crystallographic symmetry in a unit cell, including two crystallographically independent molecules, in which different orientations of the MePhNH2 groups are found. Two MePhNH2 groups are in trans position for molecule A, and cis for B. The central metal atom is in a distorted octahedral environment. The hydrogen bonds of OH(oxime)…O and NH(p-aminotoluene group)…O construct an one-dimensional chain along the c axis in the title compound.The title compound (C22H32.5ClCoN6O8.25, Mr = 607.42) crystallizes in the orthor- hombic system, space group C2221 with a = 11.320(2), b = 20.933(4), c = 23.936(5) ?
