The crystal structure described by MgTi6(N2O3)2 crystallizes in the orthorhombic Amm2 space group. Mg(1) is bonded in a 7-coordinate geometry to two equivalent N(1), one O(4), and four equivalent O(2) atoms. There are four inequivalent Ti sites. In the first Ti site, Ti(1) is bonded to two equivalent N(1), two equivalent O(2), and two equivalent O(4) atoms to form TiN2O4 octahedra that share corners with two equivalent Ti(1)N2O4 octahedra and edges with two equivalent Ti(2)N3O3 octahedra. The corner-sharing octahedral tilt angles are 3°. In the second Ti site, Ti(2) is bonded to one N(1), two equivalent N(2), one O(1), one O(2), and one O(3) atom to form distorted TiN3O3 octahedra that share corners with three equivalent Ti(2)N3O3 octahedra,  a cornercorner with one Ti(3)N2O4 pentagonal pyramid,  an edgeedge with one Ti(1)N2O4 octahedra, and edges with two equivalent Ti(3)N2O4 pentagonal pyramids. The corner-sharing octahedral tilt angles range from 30-54°. In the third Ti site, Ti(3) is bonded to two equivalent N(2), two equivalent O(1), and two equivalent O(3) atoms to form distorted TiN2O4 pentagonal pyramids that share corners with two equivalent Ti(2)N3O3 octahedra, corners with two equivalent Ti(3)N2O4 pentagonal pyramids, and edges with four equivalent Ti(2)N3O3 octahedra. The corner-sharing octahedral tilt angles are 18°. In the fourth Ti site, Ti(4) is bonded in a 6-coordinate geometry to one N(2), two equivalent N(1), one O(2), one O(3), and one O(4) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Mg(1), one Ti(1), one Ti(2), and two equivalent Ti(4) atoms to form NMgTi4 trigonal bipyramids that share  a cornercorner with one O(4)MgTi4 trigonal bipyramid, corners with two equivalent N(1)MgTi4 trigonal bipyramids, corners with three equivalent O(2)Mg2Ti3 trigonal bipyramids,  an edgeedge with one N(1)MgTi4 trigonal bipyramid, edges with two equivalent O(4)MgTi4 trigonal bipyramids, edges with three equivalent O(2)Mg2Ti3 trigonal bipyramids, and edges with two equivalent N(2)Ti4 trigonal pyramids. In the second N site, N(2) is bonded to one Ti(3), one Ti(4), and two equivalent Ti(2) atoms to form NTi4 trigonal pyramids that share  a cornercorner with one O(4)MgTi4 trigonal bipyramid, corners with three equivalent O(2)Mg2Ti3 trigonal bipyramids, corners with three equivalent N(2)Ti4 trigonal pyramids, and edges with two equivalent N(1)MgTi4 trigonal bipyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted see-saw-like geometry to two equivalent Ti(2) and two equivalent Ti(3) atoms. In the second O site, O(2) is bonded to two equivalent Mg(1), one Ti(1), one Ti(2), and one Ti(4) atom to form OMg2Ti3 trigonal bipyramids that share  a cornercorner with one O(4)MgTi4 trigonal bipyramid, corners with three equivalent N(1)MgTi4 trigonal bipyramids, corners with four equivalent O(2)Mg2Ti3 trigonal bipyramids, corners with three equivalent N(2)Ti4 trigonal pyramids, edges with two equivalent O(4)MgTi4 trigonal bipyramids, edges with three equivalent N(1)MgTi4 trigonal bipyramids, and  a faceface with one O(2)Mg2Ti3 trigonal bipyramid. In the third O site, O(3) is bonded in a T-shaped geometry to one Ti(2), one Ti(3), and one Ti(4) atom. In the fourth O site, O(4) is bonded to one Mg(1), two equivalent Ti(1), and two equivalent Ti(4) atoms to form distorted OMgTi4 trigonal bipyramids that share corners with two equivalent N(1)MgTi4 trigonal bipyramids, corners with two equivalent O(2)Mg2Ti3 trigonal bipyramids, corners with two equivalent O(4)MgTi4 trigonal bipyramids, corners with two equivalent N(2)Ti4 trigonal pyramids, edges with four equivalent N(1)MgTi4 trigonal bipyramids, and edges with four equivalent O(2)Mg2Ti3 trigonal bipyramids. is represented by the CIF file [CIF]
