Materials Data on Co(PdSe)2 by Materials Project

Abstract

Pd2CoSe2 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. Co is bonded to four equivalent Pd and four equivalent Se atoms to form distorted face-sharing CoPd4Se4 tetrahedra. All Co–Pd bond lengths are 2.86 Å. All Co–Se bond lengths are 2.34 Å. Pd is bonded in a 4-coordinate geometry to two equivalent Co, three equivalent Pd, and five equivalent Se atoms. There are one shorter (2.83 Å) and two longer (2.93 Å) Pd–Pd bond lengths. There are a spread of Pd–Se bond distances ranging from 2.52–2.88 Å. Se is bonded in a 7-coordinate geometry to two equivalent Co and five equivalent Pd atoms.
