(Sc3F10)2N2 crystallizes in the orthorhombic P222_1 space group. The structure consists of two ammonia atoms inside a Sc3F10 framework. In the Sc3F10 framework, there are three inequivalent Sc sites. In the first Sc site, Sc(1) is bonded to two equivalent F(3), two equivalent F(5), and two equivalent F(6) atoms to form ScF6 octahedra that share corners with two equivalent Sc(1)F6 octahedra, corners with two equivalent Sc(2)F7 pentagonal bipyramids, and corners with two equivalent Sc(3)F7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 7°. In the second Sc site, Sc(2) is bonded to one F(2), two equivalent F(1), two equivalent F(3), and two equivalent F(4) atoms to form ScF7 pentagonal bipyramids that share corners with two equivalent Sc(1)F6 octahedra, corners with three equivalent Sc(3)F7 pentagonal bipyramids, and  an edgeedge with one Sc(3)F7 pentagonal bipyramid. The corner-sharing octahedral tilt angles are 32°. In the third Sc site, Sc(3) is bonded to one F(2), two equivalent F(1), two equivalent F(4), and two equivalent F(6) atoms to form ScF7 pentagonal bipyramids that share corners with two equivalent Sc(1)F6 octahedra, corners with three equivalent Sc(2)F7 pentagonal bipyramids, and  an edgeedge with one Sc(2)F7 pentagonal bipyramid. The corner-sharing octahedral tilt angles are 33°. There are six inequivalent F sites. In the first F site, F(1) is bonded in a bent 120 degrees geometry to one Sc(2) and one Sc(3) atom. In the second F site, F(2) is bonded in a linear geometry to one Sc(2) and one Sc(3) atom. In the third F site, F(3) is bonded in a bent 150 degrees geometry to one Sc(1) and one Sc(2) atom. In the fourth F site, F(4) is bonded in a linear geometry to one Sc(2) and one Sc(3) atom. In the fifth F site, F(5) is bonded in a linear geometry to two equivalent Sc(1) atoms. In the sixth F site, F(6) is bonded in a bent 150 degrees geometry to one Sc(1) and one Sc(3) atom.
