[(C_2H_5)_2B(吡唑基)_2](C_7H_7)-(CO)_2Mo的结构表明,钼原子通过与乙基的α-氢原子的强相互作用(H-Mo = 1.93 A)而获得了形式上的18电子构型,从而在三庚环庚三烯环中留下了4个“未使用的“pπ电子。
The structure of [(C2H5)2B(pyrazolyl)2](C7H7)-(CO)2Mo shows that the molybdenum atom attains a formal 18-electron configuration by strong interaction with an α-hydrogen atom of an ethyl group (H–Mo = 1.93 A) thus leaving four “unused”pπ electrons in the trihaptocycloheptatrienyl ring.
