Materials Data on KPPdS4 by Materials Project
KPdPS4 crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are four shorter (3.37 Å) and four longer (3.55 Å) K–S bond lengths. There are two inequivalent Pd2+ sites. In the first Pd2+ site, Pd2+ is bonded in a square co-planar geometry to four equivalent S2- atoms. All Pd–S bond lengths are 2.35 Å. In the second Pd2+ site, Pd2+ is bonded in a square co-planar geometry to four equivalent S2- atoms. All Pd–S bond lengths are 2.36 Å. P5+ is bonded in a tetrahedral geometry to four S2- atoms. There are two shorter (2.05 Å) and two longer (2.06 Å) P–S bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded to two equivalent K1+, one Pd2+, and one P5+ atom to form a mixture of distorted corner and edge-sharing SK2PPd trigonal pyramids. In the second S2- site, S2- is bonded to two equivalent K1+, one Pd2+, and one P5+ atom to form a mixture of distorted corner and edge-sharing SK2PPd trigonal pyramids.
