Abstract

Abstract: By analyzing the MOand electronic structure for a series of sandwich cluster compounds (H₂O)₉Mo₃S₄MS₄Mo₃(H₂O)₉⁸⁺(M = Mo, Sn, Cu₂) we found that it is with the multiple center d-p π orbitals that "ligand" Mo₃S₄⁴⁺ bonds to the center atom Mto form this class clusters.The mechanism is similar to that of the formation of the classic sandwich complexes in which the ligands are conjugate organic ring.Additionally, the configurtion, the electronic spectrum and the magnetism of these sandwich clusters were accounted for on the MO's origin, and the linkage between the change in multiple center d-pπ bond and the properties of these clusters was given.
