MgRhN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Mg(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MgN4 tetrahedra that share corners with four equivalent Mg(1)N4 tetrahedra and corners with eight equivalent Rh(1)N4 tetrahedra. Rh(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form RhN4 tetrahedra that share corners with four equivalent Rh(1)N4 tetrahedra and corners with eight equivalent Mg(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Mg(1) and two equivalent Rh(1) atoms to form corner-sharing NMg2Rh2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mg(1) and two equivalent Rh(1) atoms to form corner-sharing NMg2Rh2 tetrahedra.
MgRhN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Mg(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MgN4 tetrahedra that share corners with four equivalent Mg(1)N4 tetrahedra and corners with eight equivalent Rh(1)N4 tetrahedra. There is one shorter (2.08 Å) and one longer (2.11 Å) Mg(1)-N(1) bond length. There is one shorter (2.11 Å) and one longer (2.13 Å) Mg(1)-N(2) bond length. Rh(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form RhN4 tetrahedra that share corners with four equivalent Rh(1)N4 tetrahedra and corners with eight equivalent Mg(1)N4 tetrahedra. There is one shorter (1.94 Å) and one longer (2.02 Å) Rh(1)-N(1) bond length. Both Rh(1)-N(2) bond lengths are 1.96 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Mg(1) and two equivalent Rh(1) atoms to form corner-sharing NMg2Rh2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mg(1) and two equivalent Rh(1) atoms to form corner-sharing NMg2Rh2 tetrahedra.
