Кристаллическая структура тетрабромоиндиата(III) бис-(диметилглиоксимато)дипиридинкобальта(III)

Abstract

Crystal structure of the complex in the title was determined by X-ray diffraction method, being as follows: a = 16.860(6), b=9.628(4), c=9.199(3) A, α=83.82(3)0, β=105.46(2)0, γ=100.59(2); Z=2, sp. gr. P1-bar. Two independent complexes [CoPy2(DH)2]+ (Py=C5Y5N, DH- - monoanion of dimethylglyoxime) and [InBr4]– play the role of structural units of the crystal. Coordination polyhedron of cobalt atom is a slightly elongated tetragonal bipyramid, in its equatorial plane two molecules of dimethylglyoxime and in the apical one two molecules of pyridine are located. In [InBr4]- anion indium atom is in tetrahedral surrounding of four bromide-ions
