Abstract
In the course of developing the synthesis of multinuclear heterospin coordination compounds with redoxactive ligands, a double complex salt [Na4(hfac)2Q6][Co(hfac)3]2, where hfac is hexafluoroacetylacetonate and Q is 3,6-di-tert-butyl-o-benzoquinone, was obtained. The structural feature of this salt is the presence of hfac ligands in both the cationic and anionic structural fragments, and the presence of a unique tetranuclear cation. The formation of a double complex salt is the result of the redox reaction of cobalt semiquinonate CoIII(SQ)3 with the reduction of Co(III) to Co(II) and the oxidation of semiquinonate SQ anion to quinone Q. It has been shown that in the direct interaction of Co(hfac)2 with Na(hfac) and Q a heterometal complex [NaCo(hfac)3Q2] is formed, the structure of two polymorphic modifications of which was determined by single crystal XRD.
