AbstractThe ionic Ag(I) complexes [Ph3PCH2СH=CHCH2PPh3]2+[Ag(CN)2]\(_2}^ - }\) (I) and [Ph3PR]+[Ag(CN)2]–, where R = Et (II), CHCMe2 (III), have been synthesized by the reaction between potassium dicyanoargentate and alkyltriphenylphosphonium chlorides in an aqueous solution. The IR spectra of complexes I–III have the absorption bands of CN groups at 2131–2137 cm–1. In X-ray diffraction studies,
摘要离子银(I)络合物[PH 3 PCH 2 СH= CHCH 2 PPH 3 ] 2+ [银(CN)2] \(_ 2} ^ - } \) (我)和[PH 3 PR] + [Ag(CN)2 ] –,其中R = Et(II),CHCMe 2(III),是通过水溶液中双氰基Argentate钾盐与烷基三苯基phosph氯化物之间的反应合成的。配合物I – III的红外光谱在2131–2137 cm –1处具有CN基团的吸收带。在X射线衍射研究中,发现烷基三苯基phosph阳离子具有扭曲的四面体构型:CPC角为105.6(3)°–112.8(3)°(I),108.0(3)°–110.6(4)°(II)和106.77(11)°–113.74(11)°(III),并且P–С键分别为1.790(6)–1.810(6)(I),1.774(8)–1.806(7)(II)以及1.745(3)–1.80
