These bimetallic isopropoxides undergo facile alcohol interchange with primary alcohols such as MeOH, EtOH,n-PrOH andn-BuOH. However, witht-BuOH, the reaction cannot be driven to completion even under prolonged continuous azeotropic fractionation of the liberatedi-PrOH and the final product corresponded in analysis to Cu[Ta(OPr-i)2(OBu-t)4]2.I.r., electronic and electron spin resonance spectral and magnetic susceptibility measurements indicate a distorted octahedralD 4h geometry for copper(II) in these bimetallic alkoxides.

All these derivatives have been characterised by elemental analyses, spectroscopic (IR, 1H and 13TNMR) studies as well as by molecular weight determinations.

All of these novel derivatives have been characterised by elemental analyses, molecular weight measurements, and spectroscopic [IR, NMR (1H, 13C, 27A1, 119Sn)] studies. Reactions of the derivative {Zr2(OPr-i)9}Ba{Sn(OPr-i)5} with alcohols (Me3CCH2OH and Me3COH) have been carried out to shed light on its possible structural features.

All of these coloured solid complexes have been characterised by elemental (C, H, N, and V) analyses and by spectroscopic (i.r., electronic, 1H-, 51V-n.m.r) studies. The relative lability of the hydroxy group(s) of N-(1-hydroxyethyl)naphthaldiamine, diethanolamine, and glycol has also been investigated.
