A Novel Heterobimetallic [Mg(II)-Sn(IV)]-μ-oxoisopropoxide and Its β-Diketonates: Synthesis, Analytical and Pyrolysis Studies

Abstract

In the present study, a novel heterobimetallic [Mg(II)-Sn(IV)]-μ-oxoisopropoxide [MgO₂Sn₂(OPrⁱ)₆] and its β-diketonates have been synthesized and characterized. The parent compound has been synthesized by the thermal condensation of magnesium acetate and tin(IV) isopropoxide. The isopropoxy substitution reactions of μ-oxoisopropoxide compound with β-diketones in different molar ratios (1:1–1:4) yielded the mono derivatives to tetra derivatives respectively of the parent compound. [{MgO₂Sn₂(OPrⁱ)_6-nL_n} (where n is 1–4 and L = acetylacetonate/benzoylacetonate anion)]. The μ-oxoisopropoxide compound has been characterized by liberated isopropanol, elemental, spectral (IR, ¹H, ¹³C, ¹¹⁹Sn NMR, and mass), thermal analysis, molecular weight data, and plausible structure is suggested. Some important reactions of [MgO₂Sn₂(OPrⁱ)₆] with different β-diketones have revealed interesting facets in support of the suggested structure. The β-diketonates have been characterized by elemental, liberated isopropanol and spectral analysis (IR, ¹H, ¹³C NMR).
