The title compound has an infinite three-dimensional structure that co
ntains eight-coordinate bismuth(III), five- and six-coordinate copper(
II) and four-coordinate vanadium(V). The mean bond distances are: Bi-O
2.57(31) Angstrom, Cu-O 1.956(27)(in the square planes), 2.64 (10) A
(out-of-plane distances), and V-O 1.713 (29) Angstrom. The shortest Cu
-Cu distance is 3.063 (3) Angstrom.
