In situ generation of H2Se and hydrothermal synthesis of new polynuclear rhenium carbonyl polyselenides

Two new polyselenide-bridged rhenium carbonyl complexes, [Re5(CO)18(Se2)3]− and [Re4(CO)14(Se2)(Se5)], were obtained by hydrothermal reaction of [Re(CO)5Cl] with in situ generated H2Se and have been characterized by X-ray diffraction.
