Synthesis and crystal structure of the double barium-titanium methoxide [Ba2Ti4O(OMe)18(MeOH)7]·MeOH

Abstract The X-ray diffraction study of crystals isolated from solutions obtained by reaction of Ba(OMe) 2 with Ti(OMe) 4 (molar ratio 1:2) in methyl alcohol was carried out; the crystals of the methanol solvate of the double barium-titanium methoxide, [Ba 2 Ti 4 O(OMe) 18 (MeOH) 7 ]·MeOH ( 1 ), contain two Ba 2+ cations with different environments and two kinds of anionic binuclear titanium complexes with and without oxo-ligand, and thus can be formulated as [Ba(MeOH) 2 ] 2+ [Ba(MeOH) 5 ] 2+ [Ti 2 O(OMe) 8 ] 2− [Ti 2 (OMe) 10 ] 2− ·MeOH.
