CaTcO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Ca(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. Tc(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing TcO6 octahedra. The corner-sharing octahedral tilt angles are 32°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ca(1) and two equivalent Tc(1) atoms to form distorted corner-sharing OCa2Tc2 tetrahedra. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Ca(1) and two equivalent Tc(1) atoms.
CaTcO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Ca(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. There is one shorter (2.31 Å) and one longer (2.38 Å) Ca(1)-O(1) bond length. There are a spread of Ca(1)-O(2) bond distances ranging from 2.34-2.72 Å. Tc(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing TcO6 octahedra. The corner-sharing octahedral tilt angles are 32°. Both Tc(1)-O(1) bond lengths are 2.01 Å. All Tc(1)-O(2) bond lengths are 2.02 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ca(1) and two equivalent Tc(1) atoms to form distorted corner-sharing OCa2Tc2 tetrahedra. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Ca(1) and two equivalent Tc(1) atoms.
