La2TcNiO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. La(1) is bonded to twelve equivalent O(1) atoms to form LaO12 cuboctahedra that share corners with twelve equivalent La(1)O12 cuboctahedra, faces with six equivalent La(1)O12 cuboctahedra, faces with four equivalent Tc(1)O6 octahedra, and faces with four equivalent Ni(1)O6 octahedra. Tc(1) is bonded to six equivalent O(1) atoms to form TcO6 octahedra that share corners with six equivalent Ni(1)O6 octahedra and faces with eight equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Ni(1) is bonded to six equivalent O(1) atoms to form NiO6 octahedra that share corners with six equivalent Tc(1)O6 octahedra and faces with eight equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to four equivalent La(1), one Tc(1), and one Ni(1) atom to form a mixture of distorted corner, edge, and face-sharing OLa4TcNi octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
