Synthesis, characterization, and spectroscopic properties of heterobimetallic , isopropoxides of Co, Ni and Cu containing diethanolaminate moiety

Abstract

Hydrocarbon-insoluble derivatives of the type M(deaH)₂ (M = Co, Ni, Cu(II); deaH₂ = diethanolamine) on reactions with Al(OPr<i>ⁱ</i>)₃ in 1:2 molar ratio yield hydrocarbon-soluble, monomeric heterobimetallic derivatives [{Al(OPr<i>ⁱ</i>)₂}₂M(dea)₂]· A different type of soluble heteroleptic derivatives has been prepared by the reactions of M{Al(OPr<i>ⁱ</i>)₄}₂ with deaH₂ in 1:1, 1:2 and 1:3 molar ratios. The reaction of M{Al(OPr<i>ⁱ</i>)₄}₂ with four equivalents of diethanolamine yields a benzene insoluble product of composition M {Al(dea}₂}₂. All these new derivatives have been characterized by elemental analyses, molecular weight measurements and spectroscopic (Electronic and IR) studies.
