由R的氧化制备的氧化物triorganoantimony 3的Sb(R4-CLC 6 ħ 4,4-FC 6 H ^ 4,2-CH 3 OC 6 H ^ 4,2,5-(CH 3)2 C ^ 6 ħ 3)和9-苯基-9-六氟芴,(C 6 H 5)(2,2'-C 6 H 4 C 6 H 4)Sb,具有H 2 O 2在丙酮中,由IR数据显示为固态的二聚体,并提出了具有四元SbOSbO环的结构。三(2,4,6-三甲基苯基)锑的类似氧化反应生成了二氢氧化物,其结构已通过X射线衍射确定。在该化合物中,Sb仅具有稍微变形的三角双锥体环境,其顶端具有OH基。SbO(H)键的距离为202.7(3)pm,处于共价SbO键距离的正常范围内。分子间氢键被IR和衍射数据排除。
Some new spirocycles of pentacoordinated antimony are described. By means of the temperature-dependent proton-resonance spectra of the antimony penta- organyls (XXXV) and (XXXVI) conclusions concerning the dynamic stereochemistry of these derivatives are possible. The cyclic stibines, essential for the synthesis of the pentavalent antimony derivatives, are prepared by a new method with the aid of bidentate

In contrast to the trigonal bipyramidal geometry of triphenylantimony dibromide, the related biphenyl-2,2′-diylphenylantimony dibromide has a distorted square pyramidal arrangement of ligands about antimony and is dimeric in the solid state.

Phenylbis-2,2′-biphenylyleneantimony (III) reacts with η-butyllithium to give pentabutylantimony (IV), which, after cleavage by acid is identified as the tetrabutylantimony cation. Phenyllithium reacts with the spirocycles (III) and (XII) cleaving one ring and giving products with one more phenyl group. The mixed cyclic derivative (XVI) reacts with phenyllithium and its six-membered ring is cleaved
