The first organometallic coordination compounds of heteroatom-bridged bisalkynes X(CCR)2 (1) (X = S, OS, O2S or PhP) are reported.Ten new copper(I) complexes of these ligands with halides and trifluoromethylsulphonate as anions were synthesized and characterized.The copper(I) halide complexes 4-9 were prepared by direct reaction of the copper(I) halides and the free ligands 1.The copper(I) trifluoromethylsulphonate complexes 10-13 were synthesized from the ligand 1 and CuOSO2CF3 * 0.5C6H6.The structures of these compounds, determined by spectroscopic and X-raymethods, show a variety of coordination types depending on the choice of the heteroatom X and the copper(I) fragment.In detail the following complexes were synthesized: CC(CH3)3)2>n (4); (CuCl)4 * 2OS(CCC(CH3)3)2 (5); CuCl * PhP(CCC(CH3)3)2 (6), CuA * 3PhP(CCC(CH3)3)2 (A = Cl (7) or Br (8)); CuI * 2PhP(CCC(CH3)3)2 (9), (CuOSO2CF3)2 * X(CCC(CH3)3)2 (X = S (10); OS (11) or O2S (12)); CuOSO2CF3 * Ph(CCC(CH3)3)2 (13).The structure of 4 was determined by X-ray crystallography.
