Abstract: The title compound, [Pd₄(C₈H₁₁N₂O₂)₄Cl₄]·9H₂O, is a cyclic tetramer. The Pd^II atom shows distorted square-planar coordination arising from chelation by the phenolate O atom and the pyridoxamine ligand; the metal atom is also linked to the pyridyl N atom from an adjacent ligand and a Cl atom. A twofold axis, which is parallel to the c axis, is located at the center of a tetramer. The crystal packing is stabilized by hydrogen bonding among neighboring complex molecules via the solvent water molecules.
