3-[C_2H_4（NMe_2）_2]-3，1，2-PdC_2B_9H_（11）和3，3-（PMe_3）_2 - 3，1，2-PdC_2B_9H_（11）的单晶X-射线衍射结构表明，反式配体对C_2B_9H_（11）笼的结构有显著影响，氨基化合物呈“滑移”构型，而当（PMe 3）2取代C2 H4（NMe 2）2时，观察到更对称的金属笼结合;膦化合物还显示出与已知和类似的铂衍生物3，3-（PEt 3）2- 3，1，2-PtC 2 B 9 H11的出乎意料的差异。
The molecular structures of 3-[C2H4(NMe2)2]-3,1,2-PdC2B9H11 and 3,3-(PMe3)2-3,1,2-PdC2B9H11, determined by single-crystal X-ray diffraction, reveal a marked structural influence of the ligands trans to the C2B9H11 cage, in that the amino-compound adopts a ‘slipped’ configuration, whereas when (PMe3)2 replaces C2H4(NMe2)2 much more symmetrical metal-cage binding is observed; the phosphine compound also shows unexpected differences from the known and similar platinum derivative 3,3-(PEt3)2-3,1,2-PtC2B9H11.
