Cr3(OF)2 crystallizes in the monoclinic Pc space group. There are three inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 6-coordinate geometry to one O(1), two equivalent O(2), one F(2), and two equivalent F(1) atoms. In the second Cr site, Cr(2) is bonded in a square co-planar geometry to one O(1), one O(2), one F(1), and one F(2) atom. In the third Cr site, Cr(3) is bonded in a 6-coordinate geometry to one O(2), two equivalent O(1), one F(1), and two equivalent F(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Cr(1), one Cr(2), and two equivalent Cr(3) atoms to form a mixture of edge and corner-sharing OCr4 trigonal pyramids. In the second O site, O(2) is bonded to one Cr(2), one Cr(3), and two equivalent Cr(1) atoms to form a mixture of edge and corner-sharing OCr4 trigonal pyramids. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 4-coordinate geometry to one Cr(2), one Cr(3), and two equivalent Cr(1) atoms. In the second F site, F(2) is bonded in a 4-coordinate geometry to one Cr(1), one Cr(2), and two equivalent Cr(3) atoms.
