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.
