    Abstract

    Heterobi- and heterotrimetallic complexes [NiTl(acac) 2(dmae)] 2(1) and [Ba(acac)(OH 2)Ni 2(acac) 4Tl(dmae) 2] (2) (acac = acetylacetonate, dmae = N, N-dimethyl aminoethanolate) have been synthesized by simple reactions of Ni(II) acetylacetonate, Tl(I) acetylacetonate and dmaeH for (1) and Ni(II) acetylacetonate, Tl(I) acetylacetonate, Ba metal and dmaeH for (2) in toluene to obtain crystalline products that were characterized by physicochemical and spectroscopic methods. Single-crystal X-ray analysis of both complexes shows that they crystallize in a monoclinic crystal system with space group P2 1/c. TGA studies of the complexes indicate that complex (1) is a suitable precursor for the preparation of composite NiO/Tl 2O 3, while complex (2) yields an unstable composite NiO/Tl 2O 3/BaO which on exposure to air is converted to NiO/Tl 2O 3/BaCO 3 by the absorption of atmospheric carbon dioxide.
