Synthesis and characterization of homo- and heterobimetallic triethanolaminates of Ca, Sr and Ba

The reactions of heavier alkaline earth metal alkoxides M(OPri), (M = Ca, S r Ba) with two equivalents of triethanolamine lead to the formation of inso luble products with the general formula, (H4M)-H-#{(OCH2CH2)(3)N}(2). These insoluble products when treated with Al(OPri)(3) in 1:4 molar ratio afford soluble heterobimetallic derivatives of the type {Al(OPri)(2)}(4){M[(OCH2C H2)(3)N](2)}. All these derivatives have been characterized by elemental an alysis, molecular weight measurements and spectroscopic [IR, NMR (H-1, C-13 , Al-27)] studies.
