Abstract

The bis(amidodimethyl)disiloxane ligands [O{SiMe2NR}2]2- (R = 2,6-Me2C6H3 (Ar') and 2,6-iPr2C6H3 (Ar), abbreviated [NONR]2-, are a stable support for Sb(iii) complexes of general formula Sb(NONR)X (X = Cl, H). The compounds are monomeric in the solid-state, with bidentate N,N'-coordination of the [NONR]2- and terminal chloride/hydrogen-ligands. Sb(NONAr')H was analyzed by single-crystal neutron diffraction, giving the first accurate parameters for the Sb-H bond to an antimony(iii) centre.

摘要

双（氨甲基二甲基）二硅氧烷配体[O{SiMe2NR}2]2-（R = 2,6-Me2C6H3（Ar'）和 2,6-iPr2C6H3（Ar），简称[NONR]2-）是 Sb(iii)配合物的稳定配体，其通式为 Sb(NONR)X（X = Cl，H）。这些化合物在固态中为单体，[NONR]2-和端氯/氢配体具有双齿 N，N'-配位。Sb(NONAr')H 通过单晶中子衍射进行分析，给出了 Sb(iii)中心的 Sb-H 键的首个准确参数。
