Abstract: The title complex, [Ni(C₇H₆NO₂)(C₁₀H₉N₃)(H₂O)]Cl·3H₂O, has a zigzag polymeric structure. Each Ni ion is bonded to two N atoms from a di-2-pyridylamine (BPA) ligand, two O atoms from a 4-aminobenzoic acid (p-AB) ligand, one water O atom and one amino N atom from another p-AB ligand. This is the first example of an aromatic amino N acting in a bridging role linking adjacent molecules to form a chain structure. Three water molecules and one chloride ion are also in the asymmetric unit. There are several hydrogen bonds stabilizing the crystal structure.
