Palladium(II) complexes trans-[PdCl2(3-HONC10H14O)2]⋅2H2O and trans-[PdCl2(2-HONC10H16)2] with similar formulations and molecular geometries display considerably different supramolecular arrangements due to hydrogen bonding involving the oxime substituent (NOH) of the camphor ligand, the halide co-ligand of adjacent molecules and H2O outer-sphere molecules in the case of trans-[PdCl2(3-HONC10H14O)2]⋅2H2O. The discussion is based on data collected by X-ray diffraction analysis and DFT calculations.
