  Synthesis and structure of gold and copper complexes: [Ph3PhCH2P]+[AuCl4]−, [NH(C2H4OH)3]+[AuCl4]− · H2O, and [Ph3EtP] 2 + [Cu2Cl6]2−

  摘要：

  Triphenylbenzylphosphonium tetrachloroaurate (I) and triethanolammonium tetrachloroaurate hydrate (II) were prepared by reacting tetrachloroauric acid in acetone with triphenylbenzylphosphonium and triethanolammonium, respectively. Triphenylethylphosphonium hexachlorodicuprate (III) was synthesized from triphenylethylphosphonium chloride and copper chloride in acetone. The crystal structures of complexes I to III were determined by single-crystal X-ray diffraction. The phosphorus atoms in complex I have a nearly undistorted tetrahedral coordination (CPC, 108.3 degrees-110.6 degrees; P-C, 1.788-1.793 angstrom). The coordination of nitrogen atoms in the cations of complex II is a distorted tetrahedron (CNC, 111.7 degrees-112.4 degrees). The square coordination of aurum in I and II is only slightly distorted: the ClAuCl angles are 89.6 degrees-90.3 degrees (I) and 89.5 degrees-90.6 degrees (II), and the Au-Cl distances are 2.256-2.278 angstrom (I) and 2.280-2.285 angstrom (II). The phosphorus atoms in complex III are tetracoordinated (CPC, 106.34 degrees-111.73 degrees; P-C, 1.790-1.795 angstrom). The copper atoms in III have a distorted tetrahedral coordination (ClCuCl, 98.48 degrees-144.85 degrees; Cu-Cl, 2.1999-2.3263 angstrom). The central fragment Cu2Cl2 in the anion of complex III is bent relative to the Cu-2 axis (the chlorine atom deviates from the Cu2Cl plane by 0.27 angstrom).
