The structure described by MgMnN2 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 Mn(1)N4 tetrahedra. Mn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MnN4 tetrahedra that share corners with four equivalent Mn(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 Mn(1) atoms to form corner-sharing NMg2Mn2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mg(1) and two equivalent Mn(1) atoms to form corner-sharing NMg2Mn2 tetrahedra. is represented by the CIF file [CIF]
