The compound described by TcMn2O4 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 Mn(1)O4 tetrahedra, edges with two equivalent Tc(1)O6 octahedra, and edges with four equivalent Mn(2)O6 octahedra. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form MnO4 tetrahedra that share corners with six equivalent Tc(1)O6 octahedra and corners with six equivalent Mn(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 57-60°. In the second Mn site, Mn(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MnO6 octahedra that share corners with six equivalent Mn(1)O4 tetrahedra, edges with two equivalent Mn(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 Mn(1), and one Mn(2) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Tc(1), one Mn(1), and two equivalent Mn(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
