Materials Data on K2Ta15O32 by Materials Project

Kristin Persson
K2Ta15O32 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. K1+ is bonded to twelve O2- atoms to form distorted KO12 cuboctahedra that share corners with six TaO6 octahedra, edges with three equivalent KO12 cuboctahedra, edges with three equivalent TaO6 octahedra, edges with three equivalent TaO5 square pyramids, and faces with three equivalent TaO6 octahedra. The corner-sharing octahedra tilt angles range from 40–57°. There are a spread of K–O bond distances ranging from...
