Materials Data on LaGd(ClO)2 by Materials Project

Abstract

GdLa(OCl)2 is Matlockite-derived structured and crystallizes in the tetragonal P4mm space group. The structure is three-dimensional. Gd3+ is bonded in a 4-coordinate geometry to four equivalent O2- and five Cl1- atoms. All Gd–O bond lengths are 2.31 Å. There are four shorter (3.18 Å) and one longer (3.19 Å) Gd–Cl bond lengths. La3+ is bonded in a 9-coordinate geometry to four equivalent O2- and five Cl1- atoms. All La–O bond lengths are 2.38 Å. There are one shorter (3.16 Å) and four longer (3.17 Å) La–Cl bond lengths. O2- is bonded to two equivalent Gd3+ and two equivalent La3+ atoms to form a mixture of edge and corner-sharing OLa2Gd2 tetrahedra. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 5-coordinate geometry to four equivalent Gd3+ and one La3+ atom. In the second Cl1- site, Cl1- is bonded in a 5-coordinate geometry to one Gd3+ and four equivalent La3+ atoms.
