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

The new heterobimetallic [Mg(II)-Ti(IV)]- µ -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, 1 H and 13 C NMR, and mass), thermal analysis, and molecular weight data. The reactions of [Mg(II)-Ti(IV)]- µ -oxoisopropoxide compound with β -diketones in different molar ratios (1:1–1:4) yielded mono to tetra derivatives [{MgO2 Ti2 (OPr ^i)6−nLn}] (where n is 1–4 and L = acetylacetonate/benzoylacetonate anion)] of the µ -oxo complex and were characterized by elemental, liberated isopropanol, and spectral analysis (IR and 1H and 13 C NMR). These studies revealed interesting facets in support of plausible structures of the parent compound and its β -diketonates.
