Materials Data on Sr(BiPd)2 by Materials Project

Abstract

SrPd2Bi2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Sr is bonded in a 4-coordinate geometry to eight Pd and eight Bi atoms. There are four shorter (3.58 Å) and four longer (3.77 Å) Sr–Pd bond lengths. There are four shorter (3.72 Å) and four longer (3.75 Å) Sr–Bi bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 8-coordinate geometry to four equivalent Sr and four equivalent Bi atoms. All Pd–Bi bond lengths are 2.79 Å. In the second Pd site, Pd is bonded in a 9-coordinate geometry to four equivalent Sr and five Bi atoms. There are one shorter (2.73 Å) and four longer (2.83 Å) Pd–Bi bond lengths. There are two inequivalent Bi sites. In the first Bi site, Bi is bonded in a 4-coordinate geometry to four equivalent Sr and four equivalent Pd atoms. In the second Bi site, Bi is bonded in a 5-coordinate geometry to four equivalent Sr and five Pd atoms.
