The crystal structure described by ReN2 crystallizes in the orthorhombic Cmmm space group. Re(1) is bonded to two equivalent N(2) and four equivalent N(1) atoms to form a mixture of edge and corner-sharing ReN6 octahedra. The corner-sharing octahedral tilt angles range from 27-44°. There are two inequivalent N sites. In the first N site, N(1) is bonded in a square co-planar geometry to four equivalent Re(1) atoms. In the second N site, N(2) is bonded in a trigonal planar geometry to two equivalent Re(1) and one N(2) atom. is represented by the CIF file [CIF]
