A new mixed‐ligand complex [CuL 2 (dipyam)]·3H 2 O ( 1 ) (L = lactato and dipyam = 2,2′‐dipyridylamine) has been prepared and structurally characterized by X‐ray diffraction. The presence of three crystallization water molecules creates several hydrogen‐bonded networks. Two crystallographic unique crystallization water molecules are arranged into infinite one‐dimensional chains embedded by additional hydrogen bonds between stacked complex double‐chains, but the third crystallization water molecule is apart from the chain and acts as bridge to form centrosymmetric complex tetramers.
