Reactions of CuSCN with tetramethylthiuram disulfide in CH3CN in the presence of styrene and N,N,N',N',N'-pentamethyldiethylenetriamine gave rise to a new copper(I) complex of N,N'-dimethyldithio- ca...Reactions of CuSCN with tetramethylthiuram disulfide in CH3CN in the presence of styrene and N,N,N',N',N'-pentamethyldiethylenetriamine gave rise to a new copper(I) complex of N,N'-dimethyldithio- cabamate {[Cu(S2CNMe2)]2}n. The title compound crystallized in the triclinic P-1 space group with lattice parame- ters a=0.7610(4) nm, b=0.8911(4) nm, c=0.9268(5) nm, α=68.66(1)°, β =83.88(2)°, γ=79.31(2)°, V= 0.5748(5) nm3, Z=2. The compound has a unique 1D chain structure composed of CuSCSCuSCS eight-membered rings and a pair of Cu—S bonds, the structure of which has been determined by single-crystal X-ray crystallography. The isolation of this compound may provide some helpful information for the cause of the induction periods of the reverse atom transfer radical polymerization.展开更多
