Synthesis and Structure of Cyanomethyltriphenylphosphonium Dicyanoaurate and Benzyltriphenylphosphonium Dicyanoargentate

M. Popkova,
V. Sharutin

Abstract: The interaction of potassium dicyanoaurate and dicyanoargentate with organyltriphenylphosphonium chlorides in water leads to complexes [PH3PH2CN]+[Au(CN)2]– (1) and [PH3PH2PH]+[Ag (CN)2] (2), which and structurally characterized. The phosphorus atoms in organyltriphenylphosphonium cations have a distorted tetrahedral coordination: the CPC angles equal 106.21(17)–111.02(16)° (1), 106.13(7)–111.06(7)° (2), The P-C bonds are 1.782(3)–1.818(3) Å (1) and 1.7985(16)–1.8064(16) Å (2). In the almost linear [Au(CN)2]− … Show more
