Abstract
Heterotrimetallic isopropoxides of the composition [{Zr2(OPri)9}Ba{M(OPri)3}]2 have been prepared by the in situ reactions of MCl2 [M = Be, Mg, Zn, Sn(II], Co, Ni, Cu(II), KZr2(OPri)9 and KBa(OPri)3 in equimolar amounts. Reaction of [{Zr2(OPri)9}Ba{Zn(OPri)3}]2 with tertiary butyl alcohol has been studied to gain an insight into its structure. All new derivatives have been characterised by elemental analyses, spectroscopic [IR, UV–VIS, and NMR (1H, 13C, and 119Sn)] studies and molecular weight measurements.
