Synthesis and Crystal Structure of Bis(p-aminotoluene)-bis(dimethylglyoximato) Cobalt(Ⅲ) Perchlorate
The title compound (C22H32.5ClCoN6O8.25, Mr = 607.42) crystallizes in the orthorhombic system, space group C2221 with a = 11.320(2), b = 20.933(4), c = 23.936(5)(A), V = 5672(2)(A)3, Dc = 1.423 g/cm3, Z= 8,μ(MoKo0 = 0.754 mm-1, F(000) = 2532, R = 0.0512 and wR = 0.1190.There are eight complex molecules [Co(C4H6N2O2)(C4H8N2O2)(C7H9N)2]ClO4@0.25H2O 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 octahedralenvironment. The hydrogen bonds of O-H(oxime)…O and N-H(p-aminotoluene group)…O construct an one-dimensional chain along the c axis in the title compound.
