Materials Data on KReO3 by Materials Project

KReO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. K1+ is bonded to twelve equivalent O2- atoms to form KO12 cuboctahedra that share corners with twelve equivalent KO12 cuboctahedra, faces with six equivalent KO12 cuboctahedra, and faces with eight equivalent ReO6 octahedra. All K–O bond lengths are 2.79 Å. Re5+ is bonded to six equivalent O2- atoms to form ReO6 octahedra that share corners with six equivalent ReO6 octahedra and faces with eight equivalent KO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Re–O bond lengths are 1.97 Å. O2- is bonded in a distorted linear geometry to four equivalent K1+ and two equivalent Re5+ atoms.
