Ba3PtF12 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 distorted rectangular see-saw-like geometry to four equivalent F(3) atoms. In the second Ba site, Ba(2) is bonded in a 6-coordinate geometry to two equivalent F(2), two equivalent F(3), and four equivalent F(1) atoms. Pt(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 120 degrees geometry to one Ba(2) and one F(2) atom. In the third F site, F(3) is bonded in a 3-coordinate geometry to one Ba(1), one Ba(2), and one Pt(1) atom.
Ba3PtF12 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 distorted rectangular see-saw-like geometry to four equivalent F(3) atoms. All Ba(1)-F(3) bond lengths are 2.66 Å. In the second Ba site, Ba(2) is bonded in a 6-coordinate geometry to two equivalent F(2), two equivalent F(3), and four equivalent F(1) atoms. Both Ba(2)-F(2) bond lengths are 3.03 Å.
