Rb2N3I crystallizes in the tetragonal P4/mbm space group. Rb(1) is bonded in a 8-coordinate geometry to four equivalent N(1) and four equivalent I(1) atoms. There are two inequivalent N sites. In the first N site, N(2) is bonded in a linear geometry to two equivalent N(1) atoms. In the second N site, N(1) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one N(2) atom. I(1) is bonded in a body-centered cubic geometry to eight equivalent Rb(1) atoms.
