RbVH4(OF2)2 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent O(1), four equivalent F(1), and four equivalent F(2) atoms. V(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent F(1), and two equivalent F(2) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a distorted linear geometry to one O(1) and one F(1) atom. In the second H site, H(2) is bonded in a linear geometry to one O(1) and one F(2) atom. O(1) is bonded in a distorted water-like geometry to one Rb(1), one V(1), one H(1), and one H(2) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Rb(1), one V(1), and one H(1) atom. In the second F site, F(2) is bonded in a 2-coordinate geometry to two equivalent Rb(1), one V(1), and one H(2) atom.
