Synthesis and crystal structure of bis(p-aminotoluene)-bis(dimethylglyoximato) cobalt(III) perchlorate

The title compound (C22H32.5ClCoN6O8.25, M-r = 607.42) crystallizes in the orthorhombic system, space group C222(1) with a = 11.320(2), b = 20.933(4), c 23.936(5) Angstrom, V 5672(2) Angstrom(3), D-c = 1.423 g/cm(3), Z = 8,mu(MoKalpha) = 0.754 mm(-1), F(000) = 2532, R = 0.0512 and wR = 0.1190. There are eight complex molecules [CO(C4H6N2O2)(C4H8N2O2)(C7H9N)(2)]ClO4.0.25H(2)O Of C-2 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 O-H(oxime)...O and N-H(p-aminotoluene group)...O construct an one-dimensional chain along the c axis in the title compound.
