CsMnH4(OF2)2 crystallizes in the monoclinic C2/c space group. Cs(1) is bonded in a 10-coordinate geometry to two equivalent O(1), four equivalent F(1), and four equivalent F(2) atoms. Mn(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 single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) atom. O(1) is bonded in a distorted water-like geometry to one Cs(1), one Mn(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 single-bond geometry to two equivalent Cs(1) and one Mn(1) atom. In the second F site, F(2) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one Mn(1) atom.
