characterized by elemental analyses and spectroscopic methods. Molecular structures of [RBi(S2Ctol)2] (R = Me or Ph) have been established by single crystal X-ray diffraction studies. The bismuth atom in these complexes adopts a square pyramidal configuration with the R group at the apical position. In the solid state, these complexes show supra-molecular association devoid of Bi⋯S secondary interactions. Thermolysis
已经报道了一系列单有机铋二硫代羧酸盐配合物[RBi(S 2 CAr)2 ](R = Me,Ph,tol; Ar = Ph,tol)的合成。它们已经通过元素分析和光谱学方法表征。[RBi(S 2 Ctol)2 ](R = Me或Ph)的分子结构已通过单晶X射线衍射研究确定。这些络合物中的铋原子采用方形金字塔构型,R基团位于顶端位置。在固态下,这些络合物显示出没有Bi⋯S二级相互作用的超分子缔合。[RBi(S 2 Ctol)2 ](R = Me或Ph)在回流二苯醚中的热解产生Bi 2 S 3XRD,EDAX和SEM表征的纳米晶体。络合物[PhBi(S 2 Ctol)2 ]已经用于通过AACVD沉积Bi 2 S 3的薄膜。

[MeBi(S2COMe)2] indicates that the immediate environment around the central bismuth atom is distorted square pyramidal. However, inclusion of a significant Bi⋯S intermolecular bond results in pentagonalpyramidal geometry. Thermolysis of [MeBi(S2COiPr)2] in xylene indicates that it is a good precursor for preparation of Bi2S3 at low temperature.
黄原酸酯,二硫代氨基甲酸酯和二烷基二硫代磷酸钠/钾盐与二氯化甲基铋的反应是在无水苯和[MeBi(S 2 COR)2 ]类型的产品中以化学计量比为1:2进行的(R = Me,Et,Pr i),[MeBi(S 2 CNR 2)2 ](R = Me,Et,1 / 2C 4 H 8 N)和[MeBi S 2 P(OR)2 } 2 ](R = Me,Et,Pr我)已被隔离。所有这些络合物均通过元素分析,IR和NMR(1 H,13 C和31P)光谱。[MeBi(S 2 COMe)2 ]的X射线结构表明,中心铋原子周围的周围环境扭曲成方形锥体。但是,包含显着的Bi⋯S分子间键会导致五边形金字塔形几何结构。[MeBi(S 2 CO i Pr)2 ]在二甲苯中的热解表明,它是低温制备Bi 2 S 3的良好前体。

atoms of the congeneric main-group V (15) elements into the two centrosymmetrically related (opposite) vertices of the icosahedral cage. The formulation of 2 in the [NMe4]+ salt was established unambiguously from X-ray crystallography and ascertained from a complete elemental analysis. This air-sensitive brown compound was also characterized by IR, cyclic voltammetry, negative-ion ESI mass spectrometry

(Dipp2NacNac)Ga (Dipp2NacNac = HCC(Me)N(Dipp)}2; Dipp = 2,6-iPr2C6H3) was used as a trapping reagent for the unstable compounds tBuSbH2 and MeBiH2 to yield (Dipp2NacNac)GaH(SbHtBu) (1) and (Dipp2NacNac)GaH(BiMe)}2 (2). Moreover, its reactions with a row of alkylated or arylated dichloro-bismuthenes resulted in either bridged species or the formation of a dibismuthane.
