The material described by PbCo2V2O8 crystallizes in the tetragonal I4_1cd space group. V(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form VO4 tetrahedra that share corners with six equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-56°. Co(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form CoO6 octahedra that share corners with six equivalent V(1)O4 tetrahedra and edges with two equivalent Co(1)O6 octahedra. Pb(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(4) is bonded in a 3-coordinate geometry to one V(1), one Co(1), and one Pb(1) atom. In the second O site, O(1) is bonded in a 3-coordinate geometry to one V(1), one Co(1), and one Pb(1) atom. In the third O site, O(2) is bonded in a 3-coordinate geometry to one V(1) and two equivalent Co(1) atoms. In the fourth O site, O(3) is bonded in a 3-coordinate geometry to one V(1) and two equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
