The crystal structure described by BaMgLaRuO6 crystallizes in the tetragonal I-4 space group. Ba(1) is bonded to four equivalent O(1) and eight equivalent O(2) atoms to form distorted BaO12 cuboctahedra that share corners with twelve equivalent Ba(1)O12 cuboctahedra, faces with four equivalent Mg(1)O6 octahedra, and faces with four equivalent Ru(1)O6 octahedra. Mg(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MgO6 octahedra that share corners with six equivalent Ru(1)O6 octahedra and faces with four equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-22°. La(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Ru(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form RuO6 octahedra that share corners with six equivalent Mg(1)O6 octahedra and faces with four equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-22°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ba(1), one Mg(1), two equivalent La(1), and one Ru(1) atom to form a mixture of distorted corner and edge-sharing OBa2La2MgRu octahedra. The corner-sharing octahedral tilt angles range from 0-2°. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Ba(1), one Mg(1), one La(1), and one Ru(1) atom. is represented by the CIF file [CIF]
