Synthesis, spectral, and thermoanalytical studies on the new heterobimetallic [Mg(II)-Ti(IV)]-m-oxoisopropoxide and its b-diketonates

The new heterobimetallic [Mg(II)-Ti(IV)]-m-oxoisopropoxide was synthesized on treatment of magnesium acetate with titanium(IV) isopropoxide in refluxing decalin in 1:2 molar ratio and characterized by liberated isopropanol, elemental, spectral (IR, 1H and 13C NMR, and mass), thermal analysis, and molecular weight data. The reactions of [Mg(II)-Ti(IV)]-m-oxoisopropoxide compound with b-diketones in different molar ratios (1:1--1:4) yielded mono to tetra derivatives [{MgO2Ti2(OPri)6-nLn}] (where n is 1--4 and L = acetylacetonate/benzoylacetonate anion)] of the m-oxo complex and were characterized by elemental, liberated isopropanol, and spectral analysis (IR and 1H and 13C NMR). These studies revealed interesting facets in support of plausible structures of the parent compound and its b-diketonates.
