Butterflylike frameworks are present in the isostructural clusters 1 and 2 , in which the chalcogen atom is bound as a μ 3 ligand to Co and Sn. These complexes are formed by Se/Te addition to the unbridged CoSn bond of 3 at room temperature. Compounds 1 and 2 are the first defined molecular complex compounds that contain the typical semiconductor combination Sn/E (E = Se, Te) and a ferromagnetic metal, and thus they could be of interest for applications in materials science.
