Molecular structure design approach to perspective single-source precursors of titanate materials. Synthesis, X-ray single crystal and mass-spectrometric study of M2Ti2(acac)(4)(OMe)(8), M = Mg, Co

Seisenbaeva, GA; Gohil, S; Kessler, VG


Interaction of divalent metal acetylacetonates, M(acac)(2), M = Mg, Co, with titanium methoxide, Ti(OMe)(4), in 1: 1 ratio in toluene provides with practically quantitative yield a new family of heterometallic alkoxide complexes with general composition M2Ti2(acac)(4)(OMe)(8), M = Mg (1), Co (2). The structure of these nearly spherically shaped molecules contains both metals in octahedral coordination, one acac-ligand being attached to each metal atom. Both I and 2 are highly soluble in hydrocarbon solvents and display considerable volatility with distinct fragmentation patterns starting from molecular ions in the mass-spectra, which makes them perspective precursors of titanate materials in sol-gel and MOCVD techniques.
