(CoAlF6)2N2 crystallizes in the orthorhombic Imma space group. The structure consists of four ammonia atoms inside a CoAlF6 framework. In the CoAlF6 framework, Co(1) is bonded to two equivalent F(1) and four equivalent F(3) atoms to form CoF6 octahedra that share corners with two equivalent Co(1)F6 octahedra and corners with four equivalent Al(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 40-45°. Al(1) is bonded to two equivalent F(2) and four equivalent F(3) atoms to form AlF6 octahedra that share corners with two equivalent Al(1)F6 octahedra and corners with four equivalent Co(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 34-40°. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Co(1) atoms. In the second F site, F(2) is bonded in a bent 150 degrees geometry to two equivalent Al(1) atoms. In the third F site, F(3) is bonded in a bent 150 degrees geometry to one Co(1) and one Al(1) atom.
