The material described by Ni5B2SbO10 crystallizes in the monoclinic P2/m space group. There are four inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to one O(1), one O(2), two equivalent O(4), and two equivalent O(5) atoms to form NiO6 octahedra that share  a cornercorner with one Ni(3)O6 octahedra, corners with two equivalent Sb(1)O6 octahedra, edges with two equivalent Ni(1)O6 octahedra, edges with two equivalent Ni(2)O6 octahedra, and edges with two equivalent Ni(4)O6 octahedra. The corner-sharing octahedral tilt angles range from 59-61°. In the second Ni site, Ni(2) is bonded to two equivalent O(5) and four equivalent O(1) atoms to form a mixture of corner and edge-sharing NiO6 octahedra. The corner-sharing octahedral tilt angles are 17°. In the third Ni site, Ni(3) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form NiO6 octahedra that share corners with two equivalent Ni(1)O6 octahedra, edges with two equivalent Ni(3)O6 octahedra, and edges with four equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles are 59°. In the fourth Ni site, Ni(4) is bonded to two equivalent O(4) and four equivalent O(1) atoms to form a mixture of corner and edge-sharing NiO6 octahedra. The corner-sharing octahedral tilt angles are 17°. B(1) is bonded in a trigonal planar geometry to one O(3), one O(4), and one O(5) atom. Sb(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form SbO6 octahedra that share corners with four equivalent Ni(1)O6 octahedra, edges with two equivalent Sb(1)O6 octahedra, and edges with four equivalent Ni(3)O6 octahedra. The corner-sharing octahedral tilt angles are 61°. There are five inequivalent O sites. In the first O site, O(1) is bonded to one Ni(1), two equivalent Ni(2), and two equivalent Ni(4) atoms to form ONi5 square pyramids that share corners with four equivalent O(1)Ni5 square pyramids,  a cornercorner with one O(2)Ni2Sb2 tetrahedra, and edges with four equivalent O(1)Ni5 square pyramids. In the second O site, O(2) is bonded to one Ni(1), one Ni(3), and two equivalent Sb(1) atoms to form distorted ONi2Sb2 tetrahedra that share  a cornercorner with one O(1)Ni5 square pyramid, corners with five equivalent O(2)Ni2Sb2 tetrahedra, and  an edgeedge with one O(2)Ni2Sb2 tetrahedra. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ni(3), one B(1), and one Sb(1) atom. In the fourth O site, O(4) is bonded in a distorted rectangular see-saw-like geometry to one Ni(4), two equivalent Ni(1), and one B(1) atom. In the fifth O site, O(5) is bonded in a rectangular see-saw-like geometry to one Ni(2), two equivalent Ni(1), and one B(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
