Materials Data on LaMn2CdO6 by Materials Project

Abstract

LaMn2CdO6 crystallizes in the trigonal R32 space group. The structure is three-dimensional. La3+ is bonded in a 3-coordinate geometry to nine O2- atoms. There are three shorter (2.39 Å) and six longer (2.78 Å) La–O bond lengths. Mn+3.50+ is bonded to six O2- atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedra tilt angles range from 21–27°. There is three shorter (1.97 Å) and three longer (2.00 Å) Mn–O bond length. Cd2+ is bonded in a distorted trigonal planar geometry to nine O2- atoms. There are three shorter (2.29 Å) and six longer (2.76 Å) Cd–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent La3+, two equivalent Mn+3.50+, and one Cd2+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one La3+, two equivalent Mn+3.50+, and two equivalent Cd2+ atoms.
