Materials Data on ScAg(PSe3)2 by Materials Project

ScAg(PSe3)2 crystallizes in the trigonal P-31c space group. The structure is two-dimensional and consists of two ScAg(PSe3)2 sheets oriented in the (0, 0, 1) direction. Sc3+ is bonded to six equivalent Se2- atoms to form ScSe6 octahedra that share edges with three equivalent AgSe6 octahedra. All Sc–Se bond lengths are 2.73 Å. Ag1+ is bonded to six equivalent Se2- atoms to form AgSe6 octahedra that share edges with three equivalent ScSe6 octahedra. All Ag–Se bond lengths are 2.95 Å. P4+ is bonded in a trigonal non-coplanar geometry to three equivalent Se2- atoms. All P–Se bond lengths are 2.22 Å. Se2- is bonded in a 3-coordinate geometry to one Sc3+, one Ag1+, and one P4+ atom.
