Organoantimony compounds containing

Cyclic and Polymeric Substances Containing Antimony-Antimony Bonds. A number of organoantimony compounds containing rings of four, five, or six antimony atoms have been prepared. The first such compound to be adequately characterized, tetralds-l,2,3,4-fe Y-butyltetrastibetane [47191 -73-5], C1(,H36Sb4, was obtained by the interaction of a dialkylstibide and iodine (70) ... 

Fewer organoantimony compounds containing hydrogen-bonds leading to supra-molecular self-organization have been described. It can be expected that many analogies with organotin compounds are possible and perhaps this will stimulate a search for such structures.

Organoantimony(III) and -bismuth(III) compounds containing electronegative atoms such as halogen, oxygen and so on show Lewis acidic character. Thus, tetracoordinate anions and even pentacoordinate dianions have been prepared from the corresponding halides or pseudohalides, and several of the compounds have recently been fully characterized by X-ray crystallography. Several examples are shown in equations 162 , 163 , 164 , 165 , 166 , 167 , 168 and 169 ...

Several organoantimony(III) compounds containing antimony(III)-transition metal bonds have been oxidized by elemental bromine and Ph2PCl to give the corresponding dihalides (equations 283 and 284 ). 

Andrewes et al. 2000a). It also has been shown that antimony suppresses the biomethylation of arsenic, while the latter enhances the biomethylation of antimony (Andrewes et al., 2000a). Organoantimony compounds have been isolated from the pond weed Potamogeton pectinatus and a marine diatom that contained a stibnolipid (Filella et al. 2002). 

Metallic Sb dissolves very slowly in hydrazoic acid, and owing to hydrolysis, no azide-containing products can be isolated [135]. Some organoantimony azides are known, such as the liquid (C6Hs)2SbN3, [324], which resembles the respective P and As compounds. A low azidized compound of Sb(V), the yellow...
