Abstract
Four novel M/Cu/S polymers [Et4N][MS4Cu3(S2COEt)2] (1a: M=Mo; 1b: M=W) and Et4N][MS4Cu2SEt] (2a: M=Mo; 2b: M=W) have been prepared by reactions of [Et4N]2[MS4] with CuS2COEt and CuSEt. X-ray crystal structure determinations reveal that the polymeric anions of complexes 1a and 1b both consist of MS4Cu3 building blocks linked via bidentate [S2COEt]− bridging ligands to form 1D polymeric chains. The anion structures of the polymeric compounds 2a and 2b contain MS4Cu2 repeating units which are connected via μ-SEt− ligands forming a zigzag chain running down the crystallographic b axis.
