The compound described by ReN2 crystallizes in the monoclinic C2/m space group. Re(1) is bonded to three equivalent N(2) and four equivalent N(1) atoms to form distorted ReN7 pentagonal bipyramids that share corners with four equivalent Re(1)N7 pentagonal bipyramids, corners with three equivalent N(2)Re3N tetrahedra, and edges with seven equivalent Re(1)N7 pentagonal bipyramids. There are two inequivalent N sites. In the first N site, N(1) is bonded to four equivalent Re(1) atoms to form NRe4 tetrahedra that share corners with six equivalent N(1)Re4 tetrahedra, corners with ten equivalent N(2)Re3N tetrahedra,  an edgeedge with one N(2)Re3N tetrahedra, and edges with three equivalent N(1)Re4 tetrahedra. In the second N site, N(2) is bonded to three equivalent Re(1) and one N(2) atom to form NRe3N tetrahedra that share corners with three equivalent Re(1)N7 pentagonal bipyramids, corners with two equivalent N(2)Re3N tetrahedra, corners with ten equivalent N(1)Re4 tetrahedra,  an edgeedge with one N(1)Re4 tetrahedra, and edges with two equivalent N(2)Re3N tetrahedra. is represented by the CIF file [CIF]
