Abstract

The first examples of carbonyl heterocubane-type clusters, [Fe4(μ3-Q)2(μ3-AsMe)2(CO)12] (2, Q = Se (a), Te (b)), which simultaneously contain elements of group 15 and 16, were obtained by thermolysis of [Fe3(μ3-Q)(μ3-AsMe)(CO)9] (1) in acetonitrile. The clusters 2 possess a cubic Fe4Q2As2 core with alternating Fe and Q/As atoms. The coordination environment of the Fe atoms is close to octahedral, ...
