type Cp'/sub 2/M(R)X, where M = Th, or U, Cp' = eta/sup 5/-(CH/sub3/)/sub 5/C/sub 5/, R = alkyl, aryl, or hydride, and X = alkyl, chloride, or alkoxide. The thermodynamic data were obtained by anaerobic, batch-titration, solution calorimetry from the enthalpies of solution of the organic-f-element complexes in toluene and from the subsequent enthalpies of alcoholysis with tert-butyl alcohol or methanol
钍和铀-配体键断裂焓 (D(MR)) 已被确定为一系列 Cp'/sub 2/M(R)X 类型的配合物,其中 M = Th,或 U,Cp' = eta/ sup 5/-(CH/sub 3/)/sub 5/C/sub 5/,R = 烷基、芳基或氢化物,并且 X = 烷基、氯化物或醇盐。热力学数据是通过厌氧、间歇滴定、溶液量热法从有机 f 元素配合物在甲苯中的溶液焓和随后用叔丁醇或甲醇醇解的焓获得的。
