MgCrN2 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 Cr(1)N4 tetrahedra. Cr(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CrN4 tetrahedra that share corners with four equivalent Cr(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 Cr(1) atoms to form corner-sharing NMg2Cr2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mg(1) and two equivalent Cr(1) atoms to form corner-sharing NMg2Cr2 tetrahedra.
MgCrN2 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 Cr(1)N4 tetrahedra. Both Mg(1)-N(1) bond lengths are 2.07 Å. There is one shorter (2.10 Å) and one longer (2.12 Å) Mg(1)-N(2) bond length. Cr(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CrN4 tetrahedra that share corners with four equivalent Cr(1)N4 tetrahedra and corners with eight equivalent Mg(1)N4 tetrahedra. There is one shorter (1.84 Å) and one longer (1.86 Å) Cr(1)-N(1) bond length. There is one shorter (1.86 Å) and one longer (1.87 Å) Cr(1)-N(2) bond length. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Mg(1) and two equivalent Cr(1) atoms to form corner-sharing NMg2Cr2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mg(1) and two equivalent Cr(1) atoms to form corner-sharing NMg2Cr2 tetrahedra.
