THE PECULIARITIES OF TRI(O-TOLYL)ANTIMONY AND TRI(M-TOLYL)-ANTIMONY REACTIONS WITH 2-HYDROXYBENZALDOXIME. THE MOLECULAR STRUCTURES OF TRI(O-TOLYL)ANTIMONY BIS(2-HYDROXYBENZALDOXIMATE) AND BIS(μ3-2-HYDROXYBENZALDOXIMATO-О,О',N)-(μ2-OXO)- BIS[DI(M-TOLYL)ANT

Abstract

Tri(o-tolyl)antimony bis(2-hydroxybenzaldoximate) (1) and bis(μ3-2-hydroxybenzaldoximato-О,О',N)-(μ2-oxo)-bis[di(m-tolyl)antimony] (2) were obtained by interaction of tri(o-tolyl)antimony and tri(m-tolyl)antimony with 2- hydroxybenzaldoxime in the presence of an oxidizing agent (hydrogen peroxide or tert-butyl hydroperoxide). According to the X-ray analysis data, antimony atoms are bound to oxygen atoms of axial oximate ligands in the trigonal bipyramidal coordination in two types of crystallographically independent molecules 1 a, b. In the binuclear complex 2 antimony atoms are connected by two tridentate bridging ligands and an the oxygen atom; they have the deformed octahedral coordination with С₂О₃N surroundings.
