Materials Data on CsK2Mn3P4ClO14 by Materials Project
CsK2Mn3P4O14Cl crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. Cs1+ is bonded in a 12-coordinate geometry to ten O2- and two equivalent Cl1- atoms. There are a spread of Cs–O bond distances ranging from 3.24–3.72 Å. Both Cs–Cl bond lengths are 3.87 Å. K1+ is bonded in a 9-coordinate geometry to eight O2- and one Cl1- atom. There are a spread of K–O bond distances ranging from 2.75–3.24 Å. The K–Cl bond length is 3.12 Å. There are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded to five O2- atoms to form distorted MnO5 trigonal bipyramids that share corners with five PO4 tetrahedra and an edgeedge with one MnO5 trigonal bipyramid. There are a spread of Mn–O bond distances ranging from 2.09–2.38 Å. In the second Mn2+ site, Mn2+ is bonded to four O2- and two equivalent Cl1- atoms to form MnCl2O4 octahedra that share corners with two equivalent MnCl2O4 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedral tilt angles are 0°. All Mn–O bond lengths are 2.18 Å. There are one shorter (2.72 Å) and one longer (2.74 Å) Mn–Cl bond lengths. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one MnCl2O4 octahedra, a cornercorner with one PO4 tetrahedra, and corners with two equivalent MnO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 27°. There are a spread of P–O bond distances ranging from 1.52–1.66 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one MnCl2O4 octahedra, a cornercorner with one PO4 tetrahedra, and corners with three equivalent MnO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 30°. There are a spread of P–O bond distances ranging from 1.51–1.64 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, two equivalent Mn2+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Cs1+, one Mn2+, and one P5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Cs1+, one K1+, one Mn2+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Cs1+ and two P5+ atoms. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+, one Mn2+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent K1+, one Mn2+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent K1+, one Mn2+, and one P5+ atom. Cl1- is bonded in a distorted square co-planar geometry to two equivalent Cs1+, two equivalent K1+, and two equivalent Mn2+ atoms.
