Materials Data on Pd(Se3Cl)2 by Materials Project

Abstract

Pd(Se3Cl)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one Pd(Se3Cl)2 sheet oriented in the (-1, 0, 2) direction. Pd2+ is bonded in a square co-planar geometry to two equivalent Se and two equivalent Cl1- atoms. Both Pd–Se bond lengths are 2.44 Å. Both Pd–Cl bond lengths are 2.33 Å. There are three inequivalent Se sites. In the first Se site, Se is bonded in a square co-planar geometry to two Se and two equivalent Cl1- atoms. There are one shorter (2.35 Å) and one longer (2.43 Å) Se–Se bond lengths. There are one shorter (3.07 Å) and one longer (3.48 Å) Se–Cl bond lengths. In the second Se site, Se is bonded in a water-like geometry to two Se atoms. The Se–Se bond length is 2.42 Å. In the third Se site, Se is bonded in a 1-coordinate geometry to one Pd2+ and two Se atoms. Cl1- is bonded in a distorted single-bond geometry to one Pd2+ and two equivalent Se atoms.
