  Antimony sources for MOCVD. The use of Et4Sb2 as a p-type dopant for Hg1−xCdxTe and crystal structure of the adduct [Et4Sb2 · 2CdI2]n

  摘要：

  Tetraethyldistibine, Et4Sb2, a new antimony source for MOCVD is evaluated. It is shown to be a useful and safe dopant feedstock for low temperature growth of p-type Hg1-xCdxTe. Attempted purification of Et4Sb2 by adduct formation with CdI2 resulted in isolation of a polymeric chain adduct [Et4Sb2 . 2CdI2]n (1). The structure of 1 has been determined by X-ray crystallography and consists of chains of iodide-bridged Et4Sb2 . 2CdI2 units which have CdI2 bonded to each antimony atom. Antimony and two iodine atoms form a trigonal planar arrangement around cadmium, and two weak axial bonds to the iodide atoms of adjacent units give distorted trigonal bipyramidal coordination to cadmium. The distibine molecules display a skew configuration of the ethyl substituents. The Sb(II)-Sb(II) and Sb(II)-Cd(II) distances are 2.784(2) and 2.822(2) angstrom. respectively. Dropwise addition of Me2Cd to Et4Sb2 in the absence of solvent gave an insoluble 1:1 adduct. Et4Sb2 reacts with Te but not with Cd or Hg.

  Distibines Sb2R4 react with trimethylgallane and -indane (MMe3; M = Ga, In) with formation of heterocycles of the general type [Me2MSbR‘2]3 (R‘ = Me, M = Ga (2), In (3); R‘ = i-Pr, M = Ga (4)), whereas only decomposition reactions were observed for reactions with trialkylalanes. However, the mononuclear distibine−alane adduct [Al(t-Bu)3][Sb2(i-Pr)4] (1) with the distibine serving as monodentate ligand

  Dialkylstibylsodium compounds have been prepared by cleavage of trialkylstibines with sodium in liquid ammonia. Reactions of the latter with epoxides, N-benzoylethylenimine and β-propiolactone have afforded several new functionally substituted organostibines. The different reactivities towards such cleavage of different alkly groups bound to antimony opens a route to the synthesis of asymmetrically

  通过在液体氨中用钠裂解三烷基stibines来制备二烷基stibyl钠化合物。后者与环氧化物，N-苯甲酰基亚乙基亚胺和β-丙内酯的反应提供了几种新的功能取代的有机stibines。对与锑结合的不同烷基的这种裂解的不同反应性为合成不对称取代的有机stibines开辟了一条途径。已经发现二烷基苯乙烯基钠化合物与1，2-二氯乙烷的反应中容易获得的四烷基二乙胺是合成迄今难以接近的氯二烷基锑和三氯二烷基锑化合物的合适起始原料。

  Sb2R4 (R=Me, Et) yielded the first Mg‐substituted realgar‐type Sb8 polystibides [(L1,2Mg)4(μ4,η2:2:2:2‐Sb8)] (L1=HC[C(Me)N(2,4,6‐Me3C6H2)]2, L2=HC[C(Me)N(2,6‐i‐Pr2C6H3)]2). Compounds [(L1,2Mg)2] serve both as reducing agents, initiating the cleavage of the Sb−C bonds, and as stabilizers for the resulting Sb8 polyanion. The polystibides were characterized by NMR and IR spectroscopies, elemental analysis
