MnGaH4O2F5 crystallizes in the orthorhombic Imma space group. Mn(1) is bonded to two equivalent O(1) and four equivalent F(2) atoms to form MnO2F4 octahedra that share corners with four equivalent Ga(1)F6 octahedra. The corner-sharing octahedral tilt angles are 48°. Ga(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form GaF6 octahedra that share corners with two equivalent Ga(1)F6 octahedra and corners with four equivalent Mn(1)O2F4 octahedra. The corner-sharing octahedral tilt angles range from 26-48°. H(1) is bonded in a single-bond geometry to one O(1) atom. O(1) is bonded in a distorted water-like geometry to one Mn(1) and two equivalent H(1) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to two equivalent Ga(1) atoms. In the second F site, F(2) is bonded in a distorted bent 120 degrees geometry to one Mn(1) and one Ga(1) atom.
