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]₂MS₄] 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.
