MnAs2F12 crystallizes in the tetragonal I-42d space group. Mn(1) is bonded in a 8-coordinate geometry to four equivalent F(2) and four equivalent F(3) atoms. As(1) is bonded in an octahedral geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a single-bond geometry to one As(1) atom. In the second F site, F(2) is bonded in a water-like geometry to one Mn(1) and one As(1) atom. In the third F site, F(3) is bonded in a bent 150 degrees geometry to one Mn(1) and one As(1) atom.
