Synthesis and characterization of heterobimetallic alkoxide triethanolaminate derivatives of zirconium

Novel heterobimetallic isopropoxide derivatives have been prepared by the 1:2 molar reactions of Zr(OCH2CH2)2 N(CH2CH2OH)2 with Al(OPr-i)3 or Nb(OPr-i)5 in benzene under refluxing conditions. The reactions of heterobimetallic alkoxide-triethanolaminate derivatives with chelating ligands such as acetylacetone or methoxyethanol have been investigated. All of these derivatives have been characterized by elemental analyses, molecular weight measurements and spectroscopic [IR, NMR (1H, 27Al)] studies
