The structure described by TcCo2O4 is Spinel-like structured and crystallizes in the orthorhombic Imma space group. Tc(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form TcO6 octahedra that share corners with six equivalent Co(1)O4 tetrahedra, edges with two equivalent Tc(1)O6 octahedra, and edges with four equivalent Co(2)O6 octahedra. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form CoO4 tetrahedra that share corners with six equivalent Tc(1)O6 octahedra and corners with six equivalent Co(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 53-64°. In the second Co site, Co(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CoO6 octahedra that share corners with six equivalent Co(1)O4 tetrahedra, edges with two equivalent Co(2)O6 octahedra, and edges with four equivalent Tc(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to two equivalent Tc(1), one Co(1), and one Co(2) atom. In the second O site, O(2) is bonded to one Tc(1), one Co(1), and two equivalent Co(2) atoms to form a mixture of distorted corner and edge-sharing OCo3Tc tetrahedra. is represented by the CIF file [CIF]
