Abstract

Abstract Soluble heterobimetallic-N-(hydroxyethyl) salicylaldiminate-alkoxide derivatives of the types [VO(L)2{M(OPri)n-1}] [M=Al (2) (n = 3); Ti (3), Zr (4) (n = 4); Nb (5), Ta (6) (n = 5)], [where L represents the dianionic N-(hydroxyethyl) salicylaldiminate group bonded to vanadium in a tridentate fashion involving both the oxygen atoms and azomethine nitrogen], have been prepared by the reactions of insoluble [VO(L)(LH)] (1) with different metal alkoxides in a 1:1 molar ratio in benzene. A monomeric heterobinuclear complex of the type [VO(?3-L)(-OPri)2Al(?3-L)] (7) has been prepared by the equimolar reaction of [VO(?3-L)(-OPri)]2 with [Al(?3-L) (-OPri)]2 in benzene. All these complexes have been characterised by elemental analyses, molecular weight measurements, and by spectroscopic (l.r., 1H-, 27Al- and 51V-n.m.r.) studies. The monomeric nature of (1) and (2) has been supported by their FAB-mass spectral studies. [ABSTRACT FROM AUTHOR]
