Materials Data on Cs2U(PdS2)3 by Materials Project
Cs2U(PdS2)3 crystallizes in the orthorhombic Fmmm space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 8-coordinate geometry to eight S2- atoms. All Cs–S bond lengths are 3.50 Å. In the second Cs1+ site, Cs1+ is bonded in a 10-coordinate geometry to ten S2- atoms. There are a spread of Cs–S bond distances ranging from 3.82–4.02 Å. U4+ is bonded in a distorted pentagonal pyramidal geometry to six S2- atoms. There are four shorter (2.68 Å) and two longer (2.71 Å) U–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 S2- atoms. There are two shorter (2.38 Å) and two longer (2.40 Å) Pd–S bond lengths. 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 2.37 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 6-coordinate geometry to three Cs1+, one U4+, and two Pd2+ atoms. In the second S2- site, S2- is bonded to three Cs1+, one U4+, and two equivalent Pd2+ atoms to form a mixture of distorted edge, face, and corner-sharing SCs3UPd2 octahedra. The corner-sharing octahedra tilt angles range from 26–85°.
