The crystal structure of compound (1), [CuCl(phen)(H₂NCH₂COO)]∙4H₂O, reveals an unusual hydrogen-bond water cluster aggregate T6(2)6(2). Four water molecules in (1) form an isolated water cluster, [(H₂O)14]n, resembling a "phenanthro-[1,2]phenanthrene polymer structure shape" along the ac plane. The two face-face parallel [(H₂O)14]n planes are bridged by Cl atoms in [CuCl(phen) (H₂NCH₂COO)] with a strong O-H∙∙∙Cl hydrogen bond to form a water cluster conduit.
Keywords: crystal; glycine; hydrogen-bond; nanometer sized; water cluster.
