TcO2 is Rutile-like structured and crystallizes in the monoclinic P2_1/c space group. Tc(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of corner and edge-sharing TcO6 octahedra. The corner-sharing octahedral tilt angles range from 39-51°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to three equivalent Tc(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent Tc(1) atoms.
