The compound described by Li4Ni5SbO12 crystallizes in the monoclinic C2/m space group. Li(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form edge-sharing NiO6 octahedra. In the second Ni site, Ni(2) is bonded to two equivalent O(4) and four equivalent O(1) atoms to form NiO6 octahedra that share edges with three equivalent Ni(2)O6 octahedra and edges with three equivalent Sb(1)O6 octahedra. In the third Ni site, Ni(3) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form edge-sharing NiO6 octahedra. Sb(1) is bonded to two equivalent O(4) and four equivalent O(1) atoms to form SbO6 octahedra that share edges with six equivalent Ni(2)O6 octahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), two equivalent Ni(2), and one Sb(1) atom to form distorted OLi2Ni2Sb square pyramids that share corners with three equivalent O(1)Li2Ni2Sb square pyramids, corners with two equivalent O(2)Li2Ni3 trigonal bipyramids, edges with four equivalent O(1)Li2Ni2Sb square pyramids, and  an edgeedge with one O(2)Li2Ni3 trigonal bipyramid. In the second O site, O(2) is bonded to two equivalent Li(1), one Ni(3), and two equivalent Ni(1) atoms to form distorted OLi2Ni3 trigonal bipyramids that share corners with two equivalent O(1)Li2Ni2Sb square pyramids, corners with three equivalent O(2)Li2Ni3 trigonal bipyramids,  an edgeedge with one O(1)Li2Ni2Sb square pyramid, and edges with four equivalent O(2)Li2Ni3 trigonal bipyramids. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Ni(3) and two equivalent Ni(1) atoms. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to two equivalent Ni(2) and one Sb(1) atom. is represented by the CIF file [CIF]
