Abstract

A linear mixed oxidation state trinuclear cobalt complex {CoII[(O3S)3CoIII(NH3)3]2}4- (1), having six bridging sulfito ligands, was obtained by the reaction between Na2S2O4 and an oxidized solution of CoCl2 in ammonia. The structure of 1, as found in the crystals of [(NH3)5CoSO3]4·1·16H2O, was determined by X-ray crystallography. The compound is triclinic, space group P1 with a=11.956(2), b=13.260(3), c=11.480(2) Å,α=96.50(3),β=111.86(3), γ=81.61(3)o, V=1668(1) Å3 and Z=1. Complex 1 can be regarded as two tridentate [(NH3)3Co(SO3)3]3- ligands, oxo coordinated to a Co2+ ion, forming an octahedral geometry. The dimensions of 1 correspond closely to full D3d symmetry.
