摘要：
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, [Ba2Ti4O(OMe)(18)(MeOH)(7)]. MeOH (1), contain two Ba2+ 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+)[Ti2O(OMe)(8)](2-)[Ti-2(OMe)(10)](2-).
