摘要
The cyclo‐Se7 ligand is bound to two rhenium(I) centers in the title compound 1 (depicted on the right). It arises in the reaction of [Re2I2(CO)6(thf)2] with freshly sublimed elemental selenium in CS2 and is the first complex that contains a discrete molecule of an allotropic modification of selenium as a ligand. These findings add to the understanding of the mechanism of oxidation of metals and low‐valent metal complexes by chalcogens. (Figure Presented.)
