Research on the Synthesis of New Silver Cluster Complexes by the Insertion Reaction of CS2 into Ag──S Bonds(Ⅲ)── Formation and Crystal Structure of a Trinuclear Silver Cluster Complex Ag3(Pr 3 ̄iC6H2S)3(PPh3)3·(CH3)2CHOH
【摘要】 应用CS2在Ag─S键中的单核插入物(PPh3)2Ag(S2CSPrC6H2)与CH2Cl2-PriOH混合溶剂反应,生成了一个中性的三核银簇合物。并用X射线单晶衍射法测定了其晶体结构。
【Abstract】 The title complex was prepared through the reaction of(PPh3)2Ag(S2CSPr C6H2)formed by inserting of CS2 into Ag-S bond of Ag (SPr C6H2) in the presence of PPh3 with CH2Cl2-Pr ̄iOH under mild conditions.The colorless block crystal belongs to the trigonal system with space group R3,a=2.7886(11)nm,c=1.0798(5)nm,V=5.796(4)3 nm ̄3,Dc=1.2859.cm ̄(-3),Z=3.The final R is 0.060 for 1753 reflections (F>4.0σ(F)).The core of the title compound can be considered as a planar six- membered cycle Ag3S3 of alternating silver and sulfur atoms. In addition,there exists a PriOH molecule in the unit cell.
