Materials Data on PPdSe by Materials Project
PdPSe crystallizes in the orthorhombic Pbcn space group. The structure is two-dimensional and consists of two PdPSe sheets oriented in the (0, 0, 1) direction. Pd4+ is bonded in a rectangular see-saw-like geometry to two equivalent P2- and two equivalent Se2- atoms. Both Pd–P bond lengths are 2.32 Å. There are one shorter (2.49 Å) and one longer (2.50 Å) Pd–Se bond lengths. P2- is bonded to two equivalent Pd4+, one P2-, and one Se2- atom to form corner-sharing PPPd2Se tetrahedra. The P–P bond length is 2.22 Å. The P–Se bond length is 2.31 Å. Se2- is bonded in a trigonal non-coplanar geometry to two equivalent Pd4+ and one P2- atom.
