Ba3CrF12 crystallizes in the monoclinic C2/m space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 8-coordinate geometry to four equivalent F(2) and four equivalent F(3) atoms. In the second Ba site, Ba(2) is bonded to two equivalent F(2), two equivalent F(3), and four equivalent F(1) atoms to form distorted edge-sharing BaF8 hexagonal bipyramids. Cr(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 water-like geometry to two equivalent Ba(2) atoms. In the second F site, F(2) is bonded in a bent 150 degrees geometry to one Ba(1) and one Ba(2) atom. In the third F site, F(3) is bonded in a distorted single-bond geometry to one Ba(1), one Ba(2), and one Cr(1) atom.
