A metallocene compound is represented by the formula (1):
AMX
n-1
wherein M is a transition metal atom having a coordination number of n selected from Group 3, 4, 5 or 6 of the Periodic Table of Elements, or a lanthanide metal atom, or actinide metal atom; A is a substituted monocyclic or polycyclic arenyl ligand pi-bonded to M, wherein said arenyl ligand includes at least one halogen substituent directly bonded to any sp
2
carbon atom at a bondable ring position of the ligand; and the or each X is a univalent anionic ligand, or two X are joined and bound to the metal atom to form a metallocycle ring, or two X are joined to form a chelating ligand, a diene ligand, or an alkylidene ligand.
一种金属烯化合物可以用公式(1)表示:
AMX
n-1
其中,M是具有配位数n的过渡金属原子,选自元素周期表第3、4、5或6族,或为镧系金属原子,或锕系金属原子;A是与M以π键结合的取代的单环或多元环芳基配体,其中所述芳基配体包括至少一个直接键合到配体的可键合环位上的任意sp2碳原子上的卤素取代基;而X是单价阴离子配体,或者两个X连接并与金属原子结合形成一个金属环烯环,或者两个X连接形成一个螯合配体、二烯配体或烷基亚烯配体。
