triorganoantimony oxides prepared by oxidation of R3Sb (R 4-ClC6H4, 4-FC6H4, 2-CH3OC6H4, 2,5-(CH3)2C6H3) and of 9-phenyl-9-stibafluoren, (C6H5)(2,2′-C6H4C6H4)Sb, with H2O2 in acetone, shown by IR data to be dimeric in the solid state, and a structure with a four-membered SbOSbO ring is proposed. The analogous oxidation of tris(2,4,6-trimethylphenyl)antimony produced a dihydroxide, the structure of which
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。
