引言近来,羧基桥的双核过渡金属化合物的制备和结构逐渐引起人们的注意.羧基骨架可提供较大的金属-金属间相互作用力变化范围,这正是人们兴趣之所在. 为了解Rh_2(RCOO)_4中当R不同时Rh—Rh键长变化及其对加合分子的影响,我们制备了一些Rh_2(RCOO)_4·2S型络合物(S=Py、NHEt_2、CO、NO、NO_2等)并测定了结构.Rh_2(C_6H_5COO)_4·2Py就是其中的一个. 按照Legzdins等的方法制备了Rh_2(C_6H_5COO)_4·2(CH_3)_2CO,再参照Koh等的方法将吡啶蒸气扩散到Rh_2(C_6H_5COO)_4·2(CH_3)_2CO的丙酮溶液中,经两天后得到红棕
Introduction Recently, the preparation and structure of binuclear transition metal compounds of carboxyl bridge gradually attract people’s attention.Carbon skeleton can provide a larger range of metal-metal interaction force, which is where people are interested.In order to understand Rh_2 (RCOO ) _4, we found that some Rh_2 (RCOO) _4 · 2S complexes (S = Py, NHEt_2, CO, NO, NO_2, etc.) (C_6H_5COO) _4 · 2Py is one of them.The Rh_2 (C_6H_5COO) _4 · 2 (CH_3) _2CO was prepared by the method of Legzdins et al, and the pyridine vapor was diffused into Rh_2 C_6H_5COO) _4 · 2 (CH_3) _2CO acetone solution, after two days to get reddish brown
