K3RuF12 crystallizes in the monoclinic C2/m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to four equivalent F(2) and four equivalent F(3) atoms. In the second K site, K(2) is bonded in a distorted hexagonal planar geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. Ru(1) is bonded in a body-centered cubic geometry to four equivalent F(2) and four equivalent F(3) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a bent 120 degrees geometry to one K(2) and one F(1) atom. In the second F site, F(2) is bonded in a 3-coordinate geometry to one K(1), one K(2), and one Ru(1) atom. In the third F site, F(3) is bonded in a 3-coordinate geometry to one K(1), one K(2), and one Ru(1) atom.
