Co3(OF2)2 is Hydrophilite-derived structured and crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(1), two equivalent F(1), and two equivalent F(2) atoms to form a mixture of corner and edge-sharing CoO2F4 octahedra. The corner-sharing octahedral tilt angles range from 46-53°. In the second Co site, Co(2) is bonded to two equivalent O(1), two equivalent F(1), and two equivalent F(2) atoms to form a mixture of corner and edge-sharing CoO2F4 octahedra. The corner-sharing octahedral tilt angles range from 46-53°. O(1) is bonded in a distorted trigonal planar geometry to one Co(1) and two equivalent Co(2) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted T-shaped geometry to one Co(1) and two equivalent Co(2) atoms. In the second F site, F(2) is bonded in a trigonal planar geometry to one Co(1) and two equivalent Co(2) atoms.
