Title: Materials Data on KPrPCO7 by Materials Project

Abstract

KPrCPO7 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 2.64–3.14 Å. Pr4+ is bonded to six O2- atoms to form distorted PrO6 octahedra that share corners with four equivalent PO4 tetrahedra. There are a spread of Pr–O bond distances ranging from 2.30–2.67 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.27 Å) and two longer (1.29 Å) C–O bond length. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent PrO6 octahedra. The corner-sharing octahedra tilt angles range from 37–46°. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one K1+ and one C4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one Pr4+, and one C4+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one Pr4+,more » and one C4+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Pr4+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, one Pr4+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, one Pr4+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one K1+, one Pr4+, and one P5+ atom.« less
