Co6OF11 is Hydrophilite-derived structured and crystallizes in the orthorhombic Amm2 space group. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(1), one F(1), and four equivalent F(5) atoms to form CoOF5 octahedra that share corners with four equivalent Co(4)F6 octahedra, corners with four equivalent Co(2)O2F4 octahedra, and edges with two equivalent Co(1)OF5 octahedra. The corner-sharing octahedral tilt angles range from 47-53°. In the second Co site, Co(2) is bonded to two equivalent O(1), two equivalent F(1), and two equivalent F(3) atoms to form CoO2F4 octahedra that share corners with four equivalent Co(3)F6 octahedra, corners with four equivalent Co(1)OF5 octahedra, and edges with two equivalent Co(2)O2F4 octahedra.
