Abstract

A high-temperature reactions of equimolar amounts of ReI 3 , As and S or Se with KCN following by recrystallization of the soluble products from water led to the formation of new cyanometallate cluster complexes K 7 [{Re 4 As 3 S}(CN) 12 ]·10H 2 O (1) and K 7 [{Re 4 As 3 Se}(CN) 12 ]·9.5H 2 O (2), respectively. Involvement of As 2 S 3 instead of the mixture of As and S resulted in the formation of a cluster complex K 6 [{Re 4 As 2 S 2 }(CN) 12 ]·3.5H 2 O (3). Crystal structures of the obtained compounds were investigated by the X-ray diffraction analysis. It was found that compounds 1–3 contain a new cubane cluster cores composed of the rhenium tetrahedron surrounded by the µ 3 -As and µ 3 -Q (Q = S, Se) ligands.
