voltammetry and X-ray single-crystal diffraction study. Both compounds crystallize in the monoclinic space group P 1 ¯ , which are featured in a terminal phenylimido group linked to a Mo atom of a hexamolybdate cluster by a Mo–N triple bond. Interestingly, there are two conformational isomers of the cluster anions of 1 and 2 in the crystals. By cyclic voltammetry study, their special redox properties were also
摘要两种有机-无机杂化化合物(Bu 4 N)2 [Mo 6 O 18(NAr)](Ar = 2-CH 3 -4-BrC 6 H 3(1)或2,6-CH 3 -4-通过[α-Mo8 O 26] 4-与2-甲基-4-溴苯胺盐酸盐或2,6-二甲基-4-溴苯胺盐酸盐反应的DCC脱水方案合成了BrC 6 H 2(2))。在无水乙腈中进行了表征,已通过UV-Vis光谱,1 H NMR,IR,循环伏安法和X射线单晶衍射研究对其进行了表征。两种化合物均在单斜晶空间群P 1中结晶,其特征在于末端的苯基亚酰亚胺基团通过Mo-N三键与六钼酸盐簇的Mo原子相连。有趣的是,晶体中有1和2的簇状阴离子有两个构象异构体。通过循环伏安法研究,最后还发现了它们的特殊氧化还原特性。
