The material structure described by Mg2ReN3 crystallizes in the monoclinic C2/c space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded to one N(1), one N(3), one N(4), and two equivalent N(2) atoms to form a mixture of edge and corner-sharing MgN5 trigonal bipyramids. In the second Mg site, Mg(2) is bonded to two equivalent N(2) and three equivalent N(3) atoms to form a mixture of edge and corner-sharing MgN5 trigonal bipyramids. Re(1) is bonded in a distorted see-saw-like geometry to one N(1), one N(2), one N(3), and one N(4) atom. There are four inequivalent N sites. In the first N site, N(4) is bonded to two equivalent Mg(1) and two equivalent Re(1) atoms to form a mixture of distorted edge and corner-sharing NMg2Re2 trigonal pyramids. In the second N site, N(1) is bonded in a square co-planar geometry to two equivalent Mg(1) and two equivalent Re(1) atoms. In the third N site, N(2) is bonded to two equivalent Mg(1), two equivalent Mg(2), and one Re(1) atom to form NMg4Re trigonal bipyramids that share corners with two equivalent N(2)Mg4Re trigonal bipyramids, corners with three equivalent N(3)Mg4Re trigonal bipyramids,  a cornercorner with one N(4)Mg2Re2 trigonal pyramid,  an edgeedge with one N(2)Mg4Re trigonal bipyramid, edges with three equivalent N(3)Mg4Re trigonal bipyramids, and  an edgeedge with one N(4)Mg2Re2 trigonal pyramid. In the fourth N site, N(3) is bonded to one Mg(1), three equivalent Mg(2), and one Re(1) atom to form NMg4Re trigonal bipyramids that share corners with two equivalent N(3)Mg4Re trigonal bipyramids, corners with three equivalent N(2)Mg4Re trigonal bipyramids, corners with two equivalent N(4)Mg2Re2 trigonal pyramids, edges with two equivalent N(3)Mg4Re trigonal bipyramids, and edges with three equivalent N(2)Mg4Re trigonal bipyramids. is represented by the CIF file [CIF]
