The double Barium-Titanium Isopropoxide complex is an important intermediate in the preparation of Barium Titanate, BaTiO3. The two independent complexes differ in the number of solvating alcohol molecules. The complex with four isopropanol solvent molecules (Complex A) is displayed in the applet window on the right. (It may be helpful to click on ”Hide hydrogens” at the bottom of this page). Both complexes have the same metal-oxygen core: a distorted Ba4O4 cube. Each core oxygen participates in an O-Ti(O-iPr)4 sub-unit. (Click on “Ti coordination”). Two of the Ti sub-units are trigonal bipyramidal and two are distorted square pyramidal. (Click on “Restore”). Each barium is also coordinated to an isopropanol solvent molecule. (Click on “Solvent”). In all, each barium is seven-coordinate. Click on the various “Ba coordn” buttons to explore these structures. Click on “All Ba coordn” to display the total barium coordinations. To measure a bond distance, do a double-click, double-click on two atoms. To measure a bond angle, do a double-click, single-click, double click on three atoms. (These measurements can be cleared by clicking on “Delete measurements”). |
