Materials Data on K2P2Pd by Materials Project

K2PdP2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 2-coordinate geometry to six equivalent P3- atoms. There are two shorter (3.30 Å) and four longer (3.49 Å) K–P bond lengths. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six equivalent P3- atoms. There are two shorter (3.39 Å) and four longer (3.69 Å) K–P bond lengths. Pd4+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent P3- atoms. All Pd–P bond lengths are 2.43 Å. P3- is bonded in a 9-coordinate geometry to six K1+, two equivalent Pd4+, and one P3- atom. The P–P bond length is 2.18 Å.
