Materials Data on KNd(ClO)4 by Materials Project

KNd(OCl)4 crystallizes in the orthorhombic P2_12_12 space group. The structure is three-dimensional. K is bonded in a 6-coordinate geometry to two equivalent O and four equivalent Cl atoms. Both K–O bond lengths are 3.30 Å. There are two shorter (3.04 Å) and two longer (3.63 Å) K–Cl bond lengths. Nd is bonded in a 6-coordinate geometry to two equivalent O and four Cl atoms. Both Nd–O bond lengths are 2.37 Å. There are two shorter (2.71 Å) and two longer (2.95 Å) Nd–Cl bond lengths. There are two inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to one K and one O atom. The O–O bond length is 1.24 Å. In the second O site, O is bonded in a water-like geometry to one Nd and one Cl atom. The O–Cl bond length is 1.68 Å. There are two inequivalent Cl sites. In the first Cl site, Cl is bonded in a distorted water-like geometry to one Nd and one O atom. In the second Cl site, Cl is bonded in a distorted trigonal planar geometry to two equivalent K and one Nd atom.
