dependencies for various octahedral complexes of antimony pentachloride, SbCl5L (L = donor ligand), are reported. Assignments of 35Cl resonances to axial or equatorial chlorine atoms of the SbCl5 fragment have been possible in some cases. There are no apparent systematic differences between the frequencies of the axial or equatorial chlorine atoms, such differences as there are being masked by crystal-field
报道了五氯化锑SbCl 5 L(L =供体配体)的各种八面体配合物的35-氯和121,123 Sb nqr频率及其温度依赖性。在某些情况下,可能会将35 Cl共振分配给SbCl 5片段的轴向或赤道氯原子。轴向或赤道氯原子的频率之间没有明显的系统差异,这种差异被相似大小的晶场效应所掩盖。
