Treatment of 3-(4-carboxyphenylhydrazono)pentane-2,4-dione (HL) with transition metal ions afforded four novel complexes, [Zn(L)(μ2- OOCCH3)(H2O)]n (1), [Zn(L)2(MeOH) 4] (2), {[Cd4(η2-L) 4(μ2-η2-L)4(H 2O)4(MeOH)2]·MeOH) (3) and [Cd(n 2-L)(μ2-η2-OOCCH3)(H 2O)2]n (4). Their crystal structures have been characterized by single-crystal X-ray crystallography. In polymer 1, the acetate anions bridge the Zn(II) ions forming an infinite one-dimensional (1-D) chain with L- units acting as monodentate ligands in the side chain. In mononuclear complex 2, two L- ligands act as monodentate fashion to coordinate to the Zn(II) ion. In its solid-state structure, [Zn(L) 2(MeOH)4] groups are joined together by hydrogen bonds forming a three-dimensional (3-D) supramolecular network. In tetranuclear complex 3, four Cd(II) ions are linked by four μ2- η2-L- ligands, and chelated by another four L - ligands, respectively. In polymer 4, the acetate anions bridge the Cd(II) ions leading to a 1-D chain containing chelating L- units in the side chain.
