The crystal structure described by Tc2O7 is Indium-like structured and crystallizes in the orthorhombic Pbca space group. The structure is zero-dimensional and consists of four Tc2O7 clusters. Tc(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form corner-sharing TcO4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Tc(1) atom. In the second O site, O(2) is bonded in a linear geometry to two equivalent Tc(1) atoms. In the third O site, O(3) is bonded in a single-bond geometry to one Tc(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one Tc(1) atom. is represented by the CIF file [CIF]
