The crystal structure described by Ba2La2Ni(WO6)2 crystallizes in the trigonal R-3m space group. Ba(1) is bonded in a 12-coordinate geometry to three equivalent O(2) and nine equivalent O(1) atoms. La(1) is bonded to three equivalent O(1) and nine equivalent O(2) atoms to form LaO12 cuboctahedra that share corners with six equivalent La(1)O12 cuboctahedra, faces with three equivalent La(1)O12 cuboctahedra, faces with three equivalent Ni(1)O6 octahedra, and faces with four equivalent W(1)O6 octahedra. W(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form WO6 octahedra that share corners with three equivalent Ni(1)O6 octahedra and faces with four equivalent La(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 9°. Ni(1) is bonded to six equivalent O(2) atoms to form NiO6 octahedra that share corners with six equivalent W(1)O6 octahedra and faces with six equivalent La(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 9°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Ba(1), one La(1), and one W(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Ba(1), three equivalent La(1), one W(1), and one Ni(1) atom. is represented by the CIF card [CIF]
