摘要：

The preparation and structural characterization of the dimeric Au(I) complexes of 1,1-dicyanoethene-2,2-thioseleonlate (i-mnts) and 1,1-dicyanoethene-2,2-diselenolate (i-mns), isolated as Bu4N salts, are described. They are isotype (monoclinic, space group P2(1)/c, Z=2) with lattice parameters: (Bu4N)2[Au(i-mnts)]2; a = 14.078(3) angstrom, b = 8,912(3) angstrom, c = 20.142(4) angstrom, beta = 106.32(5)-degrees; (BU4N)2[Au(i-mns)]2; a = 13.998(3) angstrom, b = 9.125(3) angstrom, c = 20.039(2) angstrom, beta = 105.12(5)-degrees. Ab initio Hartree-Fock calculations based on the experimentally determined structure yield a positive value of the Au-Au bonding order suggesting weak bonding interactions between the d10 metal centres.
