The compound described by Re2O7 is Indium-like structured and crystallizes in the orthorhombic Cmc2_1 space group. The structure is zero-dimensional and consists of four Re2O7 clusters. Re(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form corner-sharing ReO4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Re(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Re(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Re(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to two equivalent Re(1) atoms. is represented by the CIF file [CIF]
