(a) View of the CuII-POM, with the labelling of the atoms. Thermal ellipsoids are depicted at the 50% probability level, H atoms with arbitrary radii. The site occupancy factors of the two disordered parts were refined to 0.5 (turquoise and yellow). (b) Polyhedral representation of the [C6H12CuMo6N2O24]4− in the crystal structure.
