Materials Data on KPt2S3 by Materials Project

KPt2S3 crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of three KPt2S3 sheets oriented in the (0, 0, 1) direction. K1+ is bonded in a 9-coordinate geometry to three equivalent S+1.67- atoms. All K–S bond lengths are 3.37 Å. There are two inequivalent Pt2+ sites. In the first Pt2+ site, Pt2+ is bonded in an octahedral geometry to six equivalent S+1.67- atoms. All Pt–S bond lengths are 2.42 Å. In the second Pt2+ site, Pt2+ is bonded in a square co-planar geometry to four equivalent S+1.67- atoms. All Pt–S bond lengths are 2.35 Å. S+1.67- is bonded to one K1+ and three Pt2+ atoms to form a mixture of distorted edge and corner-sharing SKPt3 trigonal pyramids.

Materials Data on K2PtS2 by Materials Project

K2PtS2 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to six equivalent S2- atoms. There are two shorter (3.30 Å) and four longer (3.31 Å) K–S bond lengths. Pt2+ is bonded in a square co-planar geometry to four equivalent S2- atoms. All Pt–S bond lengths are 2.39 Å. S2- is bonded in a 8-coordinate geometry to six equivalent K1+ and two equivalent Pt2+ atoms.
