The crystal structure described by NaTi8Cu6BiO24 crystallizes in the cubic Pm-3 space group. Na(1) is bonded to twelve equivalent O(1) atoms to form NaO12 cuboctahedra that share faces with eight equivalent Ti(1)O6 octahedra. Ti(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form TiO6 octahedra that share corners with six equivalent Ti(1)O6 octahedra,  a faceface with one Na(1)O12 cuboctahedra, and  a faceface with one Bi(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 39-41°. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. In the second Cu site, Cu(2) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Bi(1) is bonded to twelve equivalent O(2) atoms to form BiO12 cuboctahedra that share faces with eight equivalent Ti(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Na(1), two equivalent Ti(1), and one Cu(2) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Ti(1), one Cu(1), and one Bi(1) atom. is represented by the CIF card [CIF]
