Materials Data on Rb2CaSb2 by Materials Project
Rb2CaSb2 crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Rb2CaSb2 cluster. Rb1+ is bonded in a single-bond geometry to one Sb2- atom. The Rb–Sb bond length is 3.37 Å. Ca2+ is bonded in a linear geometry to two equivalent Sb2- atoms. Both Ca–Sb bond lengths are 2.94 Å. Sb2- is bonded in a linear geometry to one Rb1+ and one Ca2+ atom.
