Two copper complexes with a new multi-sulfur 1, 2-dithiolene ligand, C[Cu(cddt)2] (C = tetrabutylammoni-um, n-Bu4N+; tetraphenylphosphonium, Ph4P+; cddt = 4a, 6, 7, 7a-5H cyclopenta[b]-1, 4-dithiin-2, 3 dithi-olate) have been synthesized and characterized by electrochemical studies, IR, EA, etc. The structure of (Ph4P)[Cu(cddt)2] was determined by single crystal X-ray analysis. The complex was crystallized in the triclinic, spacegroup P-1 with the cell dimensions a = 10. 460(2) A, b = 13.000(3) A, c = 16. 270(3) A, α =86. 68(3)°, β=71.92 (3)°, γ = 66.66 (3)° and Z = 2. R1 = 0. 0548, w R2 = 0. 1358 for 6786 independent reflections. The four Satoms surround the Cu atom [CuS4] core is a square-planar environment.
