Materials Data on Rb2Ti(CuS2)2 by Materials Project

Rb2Ti(CuS2)2 crystallizes in the tetragonal P4_2/mcm space group. The structure is three-dimensional. Rb1+ is bonded in a body-centered cubic geometry to eight equivalent S2- atoms. There are four shorter (3.49 Å) and four longer (3.51 Å) Rb–S bond lengths. Ti4+ is bonded to four equivalent S2- atoms to form TiS4 tetrahedra that share edges with four equivalent CuS4 tetrahedra. All Ti–S bond lengths are 2.29 Å. Cu1+ is bonded to four equivalent S2- atoms to form CuS4 tetrahedra that share corners with four equivalent CuS4 tetrahedra and edges with two equivalent TiS4 tetrahedra. All Cu–S bond lengths are 2.37 Å. S2- is bonded in a 7-coordinate geometry to four equivalent Rb1+, one Ti4+, and two equivalent Cu1+ atoms.
