Mn(BF4)2 crystallizes in the orthorhombic Pnma space group. Mn(1) is bonded to one F(1), one F(2), one F(3), two equivalent F(4), and two equivalent F(5) atoms to form distorted MnF7 pentagonal bipyramids that share corners with three equivalent B(2)F4 tetrahedra and corners with four equivalent B(1)F4 tetrahedra. There are two inequivalent B sites. In the first B site, B(1) is bonded to one F(1), one F(3), and two equivalent F(5) atoms to form BF4 tetrahedra that share corners with four equivalent Mn(1)F7 pentagonal bipyramids. In the second B site, B(2) is bonded to one F(2), one F(6), and two equivalent F(4) atoms to form BF4 tetrahedra that share corners with three equivalent Mn(1)F7 pentagonal bipyramids. There are six inequivalent F sites. In the first F site, F(6) is bonded in a single-bond geometry to one B(2) atom. In the second F site, F(1) is bonded in a distorted single-bond geometry to one Mn(1) and one B(1) atom. In the third F site, F(2) is bonded in a distorted single-bond geometry to one Mn(1) and one B(2) atom. In the fourth F site, F(3) is bonded in a distorted bent 150 degrees geometry to one Mn(1) and one B(1) atom. In the fifth F site, F(4) is bonded in a distorted bent 150 degrees geometry to one Mn(1) and one B(2) atom. In the sixth F site, F(5) is bonded in a distorted linear geometry to one Mn(1) and one B(1) atom.
