Copper(II) and cadmium(II) complexes of 2-pyridinyl-4-pyridinylmethanone: Supramolecular architectures consolidated by hydrogen bonding and π-π interaction

2-Pyridinyl-4-pyridinylmethanone (L) has been shown to behave as a monodentate ligand via its 4-pyridyl ring in three new metal(II) complexes, all of which exhibit supramolecular architectures assembled through weak interactions including hydrogen bonding and π-π stacking. Effects of the inorganic co-ligands on the structure of the Cd(II) complexes of L are also discussed.
