K2VH2OF5 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 7-coordinate geometry to two equivalent F(1), two equivalent F(3), and three equivalent F(2) atoms. V(1) is bonded in an octahedral geometry to one O(1), one F(1), two equivalent F(2), and two equivalent F(3) atoms. H(1) is bonded in a distorted single-bond geometry to one O(1) and one F(3) atom. O(1) is bonded in a distorted trigonal planar geometry to one V(1) and two equivalent H(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded to four equivalent K(1) and one V(1) atom to form distorted edge-sharing FK4V square pyramids. In the second F site, F(2) is bonded in a 4-coordinate geometry to three equivalent K(1) and one V(1) atom. In the third F site, F(3) is bonded in a 4-coordinate geometry to two equivalent K(1), one V(1), and one H(1) atom.
