A new class of group 3a organometallic compounds, containing the dichlorometallocene(III) anion [Ln(cpâ³)2Cl2]â is reported, obtained most conveniently by Clâ addition to [Ln(cpâ³)2Cl}2][cpâ³=η-C5H3(SiMe3)2]; the X-ray structure of [AsPh4][Nd(cpâ³)2Cl2] shows NdâClav. 2.668(4)Ã
and ClâNdâCl 99.3(1)°.
报道了一类新型3a族有机
金属化合物,含有二
氯合
金属(III)阴离子[Ln(cp³)2Cl2]¯,最方便地通过Cl¯与[Ln(cp³)2Cl}2][cp³=η-
C5H3(SiMe3)2]的加成反应获得;[AsPh4][Nd(cp³)2Cl2]的X射线结构表明Nd¯Cl平均键长为2.668(4) Å,Cl¯Nd¯Cl键角为99.3(1)度。
