Rb3RuF12 crystallizes in the monoclinic C2/m space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a hexagonal bipyramidal geometry to four equivalent F(1) and four equivalent F(3) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to two equivalent F(1), two equivalent F(3), and four equivalent F(2) atoms. Ru(1) is bonded in a square co-planar geometry to four equivalent F(3) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a 4-coordinate geometry to one Rb(1), one Rb(2), one F(1), and one F(2) atom. In the second F site, F(2) is bonded in a 2-coordinate geometry to two equivalent Rb(2) and one F(1) atom. In the third F site, F(3) is bonded in a distorted single-bond geometry to one Rb(1), one Rb(2), and one Ru(1) atom.
