Chloranilate bridged dinuclear copper(ii) complexes: syn–anti geometry tuned by the steric factor and supramolecular interactions

The anti-conformation of chloranilate bridged di-copper complexes of NNO donor Schiff-base ligands is more stable than the syn-conformation, but the latter is stabilised by CH⋯π and hydrogen bonding interactions between solvent of crystallisation and chloranilate moieties.
