Ca3CrF6 crystallizes in the triclinic P-1 space group. There are three inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a linear geometry to two equivalent F(2) atoms. In the second Ca site, Ca(2) is bonded in a linear geometry to two equivalent F(3) atoms. In the third Ca site, Ca(3) is bonded in a square co-planar geometry to two equivalent F(1) and two equivalent F(2) atoms. Cr(1) is bonded in a square co-planar geometry to two equivalent F(1) and two 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 one Ca(3) and one Cr(1) atom. In the second F site, F(2) is bonded in a distorted bent 120 degrees geometry to one Ca(1) and one Ca(3) atom. In the third F site, F(3) is bonded in a bent 150 degrees geometry to one Ca(2) and one Cr(1) atom.
