金屬唑

維基百科,自由的百科全書

金屬唑(又稱金屬雜茂金屬雜環戊二烯)是環戊二烯的衍生物,其中第5位置的碳原子——飽和碳——被雜原子替代。與其母體化合物不同,金屬唑從雜原子開始標數。有些化合物被描述為有機金屬化合物,但在下表中也出現幾個類金屬非金屬以進行對比。[1]許多金屬唑會發出熒光吡咯噻吩的高分子衍生物在分子電子學中成為研究對象。金屬唑可以視作吡咯結構類似物,它們包括:

一些C4H4MH金屬唑根據計算的幾何形狀和反轉障能E[2]
名稱 M d(M-C), Å d(M-H), Å α(C-M-C), ° E, kJ/mol
吡咯 N 1.37 1.01 110 0
磷唑 P 1.81 1.425 90.5 67
砷唑 As 1.94 1.53 86 125
銻唑 Sb 2.14 1.725 80.5 160
