MgSnN2 is Chalcopyrite-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 Sn(1)N4 tetrahedra. Sn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form SnN4 tetrahedra that share corners with four equivalent Sn(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 Sn(1) atoms to form corner-sharing NMg2Sn2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mg(1) and two equivalent Sn(1) atoms to form corner-sharing NMg2Sn2 tetrahedra.

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 Sn(1)N4 tetrahedra. There is one shorter (2.09 Å) and one longer (2.10 Å) Mg(1)-N(1) bond length. There is one shorter (2.10 Å) and one longer (2.11 Å) Mg(1)-N(2) bond length. Sn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form SnN4 tetrahedra that share corners with four equivalent Sn(1)N4 tetrahedra and corners with eight equivalent Mg(1)N4 tetrahedra. There is one shorter (2.07 Å) and one longer (2.08 Å) Sn(1)-N(1) bond length. Both Sn(1)-N(2) bond lengths are 2.07 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Mg(1) and two equivalent Sn(1) atoms to form corner-sharing NMg2Sn2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mg(1) and two equivalent Sn(1) atoms to form corner-sharing NMg2Sn2 tetrahedra.
