BaLaNiRuO6 crystallizes in the tetragonal I-4 space group. Ba(1) is bonded to four equivalent O(2) and eight equivalent O(1) atoms to form BaO12 cuboctahedra that share corners with twelve equivalent Ba(1)O12 cuboctahedra, faces with four equivalent Ru(1)O6 octahedra, and faces with four equivalent Ni(1)O6 octahedra. 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(2) and four equivalent O(1) atoms to form RuO6 octahedra that share corners with six equivalent Ni(1)O6 octahedra and faces with four equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-22°. Ni(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form NiO6 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°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Ba(1), one La(1), one Ru(1), and one Ni(1) atom. In the second O site, O(2) is bonded to two equivalent Ba(1), two equivalent La(1), one Ru(1), and one Ni(1) atom to form a mixture of distorted corner and edge-sharing OBa2La2NiRu octahedra. The corner-sharing octahedral tilt angles range from 0-2°.
