Materials Data on KCu3P3(O4F3)2 by Materials Project
Abstract
KCu3P3(O4F3)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. K1+ is bonded in a 10-coordinate geometry to four O2- and six F1- atoms. There are two shorter (2.73 Å) and two longer (3.08 Å) K–O bond lengths. There are four shorter (3.01 Å) and two longer (3.22 Å) K–F bond lengths. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to four O2- and two equivalent F1- atoms to form distorted CuO4F2 octahedra that share corners with three CuO4F2 octahedra, corners with four PO2F2 tetrahedra, and a faceface with one CuO4F2 octahedra. The corner-sharing octahedra tilt angles range from 49–62°. There are a spread of Cu–O bond distances ranging from 1.97–2.01 Å. There are one shorter (2.16 Å) and one longer (2.50 Å) Cu–F bond lengths. In the second Cu2+ site, Cu2+ is bonded to four O2- and two equivalent F1- atoms to form distorted CuO4F2 octahedra that share corners with two equivalent CuO4F2 octahedra, corners with four equivalent PO3F tetrahedra, and faces with two equivalent CuO4F2 octahedra. The corner-sharing octahedral tilt angles are 49°. There are two shorter (2.06 Å) and two longer (2.45 Å) Cu–O bond lengths. Both Cu–F bondmore »

There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a 2-coordinate geometry to three Cu2+ atoms. In the second F1- site, F1- is bonded in a single-bond geometry to two equivalent K1+ and one P5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one K1+ and one P5+ atom.},
