Индийсодержащие диоксиматы кобальта(III)

Abstract

Indium-containing cobalt(III) dioximates were synthesized. On the basis of data of element and X-ray phase analysis, magnetochemical, IR spectroscopic and thermogravimetric studies, it was ascertained that they present compounds of the composition: [CoA2•(DH)2][InBr4] and [CoA2(DioximH)2][InA2Cl4] (A - C5H5N, 2-, 3-, 4-CH3C5H4N; DioximH- - monoanion dimethyl (DH)-, diphenyl (DphH)- or 1,2-cyclohexanediondioxim). Thermal transformations of the latter during heating up to 130-140 deg C were lead to the formation [CoA2(DioximH)2][InCl4]. The compounds [Co(C5H5N)2(DH)2][In(C5H5N)2Cl4] and [Co(4-CH3C5H4N)2(DphH)2][In(4-CH3C5H4N)2Cl4] were studied by the X-ray diffraction analysis (R = 0,045 and 0,070 corresponding)
