Materials Data on Rb2Pd3Se4 by Materials Project

Abstract

Rb2Pd3Se4 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight equivalent Se2- atoms. There are a spread of Rb–Se bond distances ranging from 3.76–3.82 Å. There are two inequivalent Pd2+ sites. In the first Pd2+ site, Pd2+ is bonded in a square co-planar geometry to four equivalent Se2- atoms. There are two shorter (2.49 Å) and two longer (2.50 Å) Pd–Se bond lengths. In the second Pd2+ site, Pd2+ is bonded in a square co-planar geometry to four equivalent Se2- atoms. All Pd–Se bond lengths are 2.50 Å. Se2- is bonded in a 7-coordinate geometry to four equivalent Rb1+ and three Pd2+ atoms.
