  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.

• Peroxides of elements other than carbon. Part XVII. The reaction of trialkylstibines and trialkylbismuthines with t-butyl hydroperoxide and with oxygen

  t-Butyl hydroperoxide reacts with trialkylstibines, R3M, to give the corresponding stibine oxides, R3MO, but with trialkylbismuthines to give products such as RO·OBut, ROH, and ROR. Both reactions are thought to involve the intermediate metallonium ion R3MOH, which undergoes nucleophilic attack on H when M = Sb, and on R when M = Bi.

  叔丁基氢过氧化物与三烷基stibines R 3 M反应，生成相应的氧化锑，R 3 MO，但与三烷基双变色氨酸生成RO·OBu t，ROH和ROR等产物。认为这两个反应都涉及中间体金属离子R 3 MOH，当M = Sb时，它对H发生亲核攻击，而当M = Bi时，对R发生亲核攻击。

  Thermally stable dialkylantimony(V) compounds of the type R2SbX3 (X= OMe, OEt, or OAc) have been prepared in good yields and purity. Hydrolysis of the trialkoxodialkylantimony compounds, R2Sb(OR′)3, results in the quantitative formation of hydroxo(oxo)dialkylantimony compounds, R2Sb(O)OH. These compounds are thermally stable and not sensitive towards oxygen in the air. Therefore, they form suitable

  Et2SbTeEt involved the reaction of Et2SbBr with EtTeLi. The compounds are light sensitive, and some of them cannot be obtained pure because of facile radical decomposition or reverse dissociation to the corresponding R4E2 and R′2Te2. Thermal degradation of Et2SbTeEt in a hydrogen stream under conventional MOCVD condition gives a metal deposit containing Sb and Te in the ratio 1.6:1. The related compound
