thumb|150px|General chemical structure of a metallocene compound, where M is a metal cation A metallocene is a compound typically consisting of two cyclopentadienyl anions (, abbreviated Cp) bound to a metal center (M) in the oxidation state II, with the resulting general formula Closely related to the metallocenes are the metallocene derivatives, e.g. titanocene dichloride or vanadocene dichloride. Certain metallocenes and their derivatives exhibit catalytic properties, although metallocenes are rarely used industrially. Cationic group 4 metallocene derivatives related to [Cp2ZrCH3]+ catalyze
茂金属(英语:metallocene)是一类有机金属化合物,典型的是由两个环戊二烯阴离子(茂基,简写为Cp,即C5H5-)和二价氧化态金属中心连接而成,通式为(C5H5)2M。 与茂金属密切相关的为茂金属衍生物,如二氯二茂钛、二氯二茂钒等。 某些茂金属及其衍生物表现出催化剂的性质,尽管在工业生产中很少用到。如[Cp2ZrCH3]+相关的第四族元素阳离子茂衍生物,可以催化烯烃聚合。茂金属属于夹心型配合物中的一类。 右侧的茂金属结构示意图中,两个五边形表示两个环戊二烯离子,五边形中的圆圈表示这个结构稳定且具有芳香性。图中所示的构象为。
