The compound described by ReN2 crystallizes in the monoclinic Pm space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 6-coordinate geometry to one N(3), one N(4), two equivalent N(1), and two equivalent N(2) atoms. In the second Re site, Re(2) is bonded to one N(1), two equivalent N(2), two equivalent N(3), and two equivalent N(4) atoms to form distorted ReN7 pentagonal bipyramids that share corners with two equivalent N(4)Re3N tetrahedra and faces with two equivalent Re(2)N7 pentagonal bipyramids. There are four inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal planar geometry to one Re(2) and two equivalent Re(1) atoms. In the second N site, N(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Re(1) and two equivalent Re(2) atoms. In the third N site, N(3) is bonded in a distorted rectangular see-saw-like geometry to one Re(1), two equivalent Re(2), and one N(4) atom. In the fourth N site, N(4) is bonded to one Re(1), two equivalent Re(2), and one N(3) atom to form NRe3N tetrahedra that share corners with two equivalent Re(2)N7 pentagonal bipyramids and corners with two equivalent N(4)Re3N tetrahedra. is represented by the CIF file [CIF]
