The material described by RhN2 is Marcasite structured and crystallizes in the monoclinic P2_1/c space group. Rh(1) is bonded to three equivalent N(1) and three equivalent N(2) atoms to form RhN6 octahedra that share corners with eight equivalent Rh(1)N6 octahedra, corners with three equivalent N(1)Rh3N tetrahedra, corners with three equivalent N(2)Rh3N tetrahedra, and edges with two equivalent Rh(1)N6 octahedra. The corner-sharing octahedral tilt angles range from 68-70°. There are two inequivalent N sites. In the first N site, N(1) is bonded to three equivalent Rh(1) and one N(2) atom to form NRh3N tetrahedra that share corners with three equivalent Rh(1)N6 octahedra, corners with four equivalent N(1)Rh3N tetrahedra, corners with nine equivalent N(2)Rh3N tetrahedra, and  an edgeedge with one N(1)Rh3N tetrahedra. The corner-sharing octahedral tilt angles range from 65-68°. In the second N site, N(2) is bonded to three equivalent Rh(1) and one N(1) atom to form NRh3N tetrahedra that share corners with three equivalent Rh(1)N6 octahedra, corners with four equivalent N(2)Rh3N tetrahedra, corners with nine equivalent N(1)Rh3N tetrahedra, and  an edgeedge with one N(2)Rh3N tetrahedra. The corner-sharing octahedral tilt angles range from 63-64°. is represented by the CIF card [CIF]
