The structure described by V3O8N2 crystallizes in the tetragonal P4/mbm space group. The structure consists of four ammonia atoms inside a V3O8 framework. In the V3O8 framework, there are two inequivalent V sites. In the first V site, V(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form VO6 octahedra that share corners with two equivalent V(1)O6 octahedra and corners with four equivalent V(2)O5 trigonal bipyramids. The corner-sharing octahedra are not tilted. In the second V site, V(2) is bonded to one O(4), two equivalent O(2), and two equivalent O(3) atoms to form VO5 trigonal bipyramids that share corners with two equivalent V(1)O6 octahedra and corners with three equivalent V(2)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 12°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent V(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent V(2) atoms. In the third O site, O(3) is bonded in a linear geometry to one V(1) and one V(2) atom. In the fourth O site, O(3) is bonded in a linear geometry to one V(1) and one V(2) atom. In the fifth O site, O(3) is bonded in a linear geometry to one V(1) and one V(2) atom. In the sixth O site, O(4) is bonded in a linear geometry to two equivalent V(2) atoms. is represented by the CIF file [CIF]
