MgRuN2 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 Ru(1)N4 tetrahedra. Ru(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form RuN4 tetrahedra that share corners with four equivalent Ru(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 Ru(1) atoms to form corner-sharing NMg2Ru2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mg(1) and two equivalent Ru(1) atoms to form corner-sharing NMg2Ru2 tetrahedra.
MgRuN2 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 Ru(1)N4 tetrahedra. There is one shorter (2.09 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. Ru(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form RuN4 tetrahedra that share corners with four equivalent Ru(1)N4 tetrahedra and corners with eight equivalent Mg(1)N4 tetrahedra. There is one shorter (1.92 Å) and one longer (1.97 Å) Ru(1)-N(1) bond length. Both Ru(1)-N(2) bond lengths are 1.95 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Mg(1) and two equivalent Ru(1) atoms to form corner-sharing NMg2Ru2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mg(1) and two equivalent Ru(1) atoms to form corner-sharing NMg2Ru2 tetrahedra.
