Crystal structure of cage complex Pd2(stable E-1)4 (top left) and DFT optimized structures of cage complexes Pd2(stable E-1)4, Pd2(stable Z-1)4 and Pd2(unstable Z-1)4. For clarity only one of the enantiomeric cages was depicted on the figure (carbon – black, nitrogen – blue, oxygen – red, palladium – cyan, chlorine – green, hydrogen – white).
