Abstract
The synthesis of a heteroligand complex of CuCl with triphenylphosphine and 5-pyridine-4-yl-5,6-dihydro-[1,3]dithiolo[4,5-b][1,4]dithiine-2-thione (L) of composition { [CuCl(PPh3)(L)](CH3 CN)}2 (I) is described. The crystals of complex I are triclinic: space group \(P\bar 1\), a = 8.928(2) A, b = 13.872(3) A, c = 14.470(3) A, α = 72.89(3)°, β = 88.41(3)°, γ = 77.02(3)°, and Z = 2. The Cu(1) atom has a quasi-tetrahedral environment including the phosphorus atom of the triphenylphosphine molecule, nitrogen atom of the pyridyl radical of molecule L, and two bridging chloride ions. The fact that noncoordinated sulfur atoms are present can be used for the further interaction of complex I with soft Lewis acids.
