Materials Data on KBiPCO7 by Materials Project
KCBiPO7 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.60–2.95 Å. C3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of C–O bond distances ranging from 1.27–1.31 Å. Bi5+ is bonded to six O2- atoms to form distorted BiO6 octahedra that share corners with four equivalent PO4 tetrahedra. There are a spread of Bi–O bond distances ranging from 2.28–2.44 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent BiO6 octahedra. The corner-sharing octahedra tilt angles range from 40–48°. All P–O bond lengths are 1.56 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one K1+ and one C3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one C3+, and one Bi5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one C3+, and one Bi5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Bi5+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, one Bi5+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, one Bi5+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, one Bi5+, and one P5+ atom.
