The material described by V3(Bi4O11)2 crystallizes in the triclinic P-1 space group. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(3), one O(6), one O(7), and one O(8) atom to form corner-sharing VO4 tetrahedra. The corner-sharing octahedral tilt angles are 53°. In the second V site, V(2) is bonded to two equivalent O(5), two equivalent O(7), and two equivalent O(9) atoms to form corner-sharing VO6 octahedra. There are four inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 8-coordinate geometry to one O(3), one O(5), one O(7), one O(9), two equivalent O(1), and two equivalent O(11) atoms.

In the first O site, O(1) is bonded to one Bi(3), one Bi(4), and two equivalent Bi(1) atoms to form a mixture of corner and edge-sharing OBi4 tetrahedra. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Bi(3), one Bi(4), and two equivalent Bi(2) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to one V(1), one Bi(1), and one Bi(3) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one Bi(2) and one Bi(3) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one V(2), one Bi(1), and one Bi(3) atom. In the sixth O site, O(6) is bonded in a distorted bent 150 degrees geometry to one V(1) and one Bi(4) atom. In the seventh O site, O(7) is bonded in a 2-coordinate geometry to one V(1), one V(2), one Bi(1), and one Bi(4) atom. In the eighth O site, O(8) is bonded in a distorted single-bond geometry to one V(1), one Bi(2), and one Bi(4) atom. In the ninth O site, O(9) is bonded in a distorted single-bond geometry to one V(2), one Bi(1), and one Bi(4) atom.
