Materials Data on RbNd(ClO)4 by Materials Project

RbNd(OCl)4 crystallizes in the orthorhombic P2_12_12 space group. The structure is three-dimensional. Rb is bonded in a 8-coordinate geometry to four O and four equivalent Cl atoms. There are two shorter (3.26 Å) and two longer (3.48 Å) Rb–O bond lengths. There are two shorter (3.18 Å) and two longer (3.69 Å) Rb–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 2.38 Å. There are two shorter (2.70 Å) and two longer (2.97 Å) Nd–Cl bond lengths. There are two inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to one Rb and one O atom. The O–O bond length is 1.23 Å. In the second O site, O is bonded in a distorted water-like geometry to one Rb, 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 Rb and one Nd atom.

Materials Data on Rb3Nd(Cl3O)2 by Materials Project

Rb3Nd(OCl3)2 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. there are three inequivalent Rb sites. In the first Rb site, Rb is bonded to six Cl atoms to form distorted face-sharing RbCl6 pentagonal pyramids. There are three shorter (3.37 Å) and three longer (3.63 Å) Rb–Cl bond lengths. In the second Rb site, Rb is bonded in a 8-coordinate geometry to one O and seven Cl atoms. The Rb–O bond length is 3.12 Å. There are a spread of Rb–Cl bond distances ranging from 3.16–3.84 Å. In the third Rb site, Rb is bonded in a distorted hexagonal planar geometry to six equivalent Cl atoms. All Rb–Cl bond lengths are 3.25 Å. Nd is bonded in a 2-coordinate geometry to two equivalent O and six Cl atoms. Both Nd–O bond lengths are 2.47 Å. There are a spread of Nd–Cl bond distances ranging from 2.83–2.91 Å. O is bonded in a 1-coordinate geometry to one Rb and one Nd atom. There are four inequivalent Cl sites. In the first Cl site, Cl is bonded in a distorted rectangular see-saw-like geometry to four Rb atoms. In the second Cl site, Cl is bonded in a 5-coordinate geometry to four Rb and one Nd atom. In the third Cl site, Cl is bonded in a 3-coordinate geometry to four equivalent Rb and one Nd atom. In the fourth Cl site, Cl is bonded to two Rb and two equivalent Nd atoms to form a mixture of corner and edge-sharing ClRb2Nd2 tetrahedra.
