CuSbO4 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a rectangular see-saw-like geometry to one O(1), one O(3), one O(5), and one O(7) atom. In the second Cu site, Cu(2) is bonded in a 5-coordinate geometry to one O(4), one O(6), one O(8), and two equivalent O(2) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to one O(1), one O(2), one O(7), and two equivalent O(4) atoms to form edge-sharing SbO5 trigonal bipyramids. In the second Sb site, Sb(2) is bonded to one O(3), one O(6), one O(8), and two equivalent O(5) atoms to form distorted edge-sharing SbO5 trigonal bipyramids. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Cu(1) and one Sb(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Cu(2) and one Sb(1) atom.

In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one Cu(2) and one Sb(2) atom. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to one Cu(1) and one Sb(1) atom. In the eighth O site, O(8) is bonded in a bent 120 degrees geometry to one Cu(2) and one Sb(2) atom.
