CuReO4 is Keatite-derived structured and crystallizes in the tetragonal I4_1cd space group. Re(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form ReO4 tetrahedra that share corners with four equivalent Cu(1)O4 trigonal pyramids. Cu(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form distorted CuO4 trigonal pyramids that share corners with four equivalent Re(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Re(1) and one Cu(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Re(1) and one Cu(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Re(1) and one Cu(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Re(1) and one Cu(1) atom.
