Syntheses, Crystal Structures, Luminescent and Magnetic Properties of One OD Zinc(II) and Two 1D Manganese(II) Coordination Compounds Assembled from Pyridine-Tricarboxylate Blocks

One OD zinic(II) and two 1D manganese(11) coordination compounds, namely [Zn(H(2)biim)(2)(H2O)(2)][Zn(HL) (Hbiim)(H2O)}(2)center dot 8H(2)O (1), [Mn(mu-HL)(phen)(H2O)](n) (2) and {[Mn(mu-HL)(2,2'-bipy)(H2O)]center dot 0.5(2,2'-bipy)}(n) (3) have been constructed hydrothermally using H3L (H3L=4-(6-carboxy-pyridin-3-yl)-isophthalic acid), H(2)biim (H(2)biim= 2,2'-biimidazole), phen (phen=1,10-phenanthroline), 2,2'-bipy (2,2'-bipy=2,2'-bipyridine), and zinc or manganese chlorides. Single-crystal X-ray diffraction analyses reveal that three compounds crystallize in the monoclinic system, space groups P2(1)/n or P2(1)/c. Compound 1 shows a OD structure composed of three monomer Zn(II) units, which is arranged into a 3D supramolecular framework through O-H center dot center dot center dot O/N or N-H center dot center dot center dot O hydrogen bonds. Compounds 2 and 3 feature a 1D metal-organic chain, which is assembled to a 2D supramolecular network through O-H center dot center dot center dot O hydrogen bond. The luminescent and magnetic properties for three compounds were also investigated. CCDC: 1917771, 1; 1917772, 2; 1917773, 3.
