If titanium is described as occupying holes in Ba-O lattice, what type of holes does it occupy? — Solid State Chemistry Question

💡 Solution & Explanation

The barium ions at the corners and oxide ions at the face centers form a close-packed arrangement. The titanium ion at the body center is surrounded by 6 oxide ions at the face centers, which forms an octahedral coordination geometry. Thus, it occupies an octahedral void.
