Abstract The reaction of copper(I) bromide, CuBr, with the tetraalkylthiurammonosulfides R4tms (R = iPr, nPr) affords the copper(I) complexes iPr4tmsCuBr (I) (C14H28BrCuN2S2, orthorhombic, Pna21, Z = 4, a = 12.487(2), b = 12.699(2), c = 12.742(2) Å) and nPr4tmsCuBr (II) (C14H28BrCuN2S3, monoclinic, P21/n, Z = 4, a = 9.092(5), b = 23.408(11), c = 10.082(7) Å, β = 104.90(5)°), which exist in the solid as monomeric units featuring three-coordinate copper(I). The ligands are bidentate and coordination is completed by the bromine atoms. The configurations of the six-membered metal-ligand ring in (I) and (II) are more severely distorted than the previously reported structurally related complexes of ethyl series. The crystal structural studies are complemented and confirmed by IR and 1H-NMR spectroscopies, as well as room temperature, magnetic, solution conductivity, and molecular weight studies.
