Complexes of osmium halides with donor ligands L (L = PPh3, AsPh3, SbPh3, PMePh2, C2H4(AsPh2)2, PPr2nPh, CH2(AsPh2)2) have been prepared. The IR and NMR spectra of complexes of the type trans-[OsCl4L2], fac-[OsX3L3] and trans-[OsX2L4] are recorded and discussed. For the trans complexes the halogen sensitive modes occur near those of the related [OsX4]2− species. Tentative assignments for ν(OsY) (Y
制备了卤化with与供体配体L(L = PPh 3,AsPh 3,SbPh 3,PMePh 2,C 2 H 4(AsPh 2)2,PPr 2 n Ph,CH 2(AsPh 2)2)的配合物。记录并讨论了反式-[OsCl 4 L 2 ],fac- [OsX 3 L 3 ]和反式-[OsX 2 L 4 ]类型的配合物的IR和NMR光谱。为了反式配合物卤素敏感模式发生在相关的[OsX 4 ] 2-物种附近。在实验结果的基础上讨论了ν(Os(Y)(Y = P,As,Sb)的暂定分配。记录并讨论了所选配合物的拉曼光谱和ESR光谱。NMR数据表明在反式-(OsCl 4(CH 2(AsPh 2)2)2)·C 2 H 5 OH中存在单齿二砷配体。
