A new coordination polymer (CP), namely, poly[[diaquatris[μ2-1,4-bis(1H-imidazol-1-yl)benzene]bis[μ6-4-(2,4-dicarboxylatophenoxy)phthalato]tetracobalt(II)] hexahydrate], {[Co4(C16H6O9)2(C12H10N4)3(H2O)2]·6H2O} n , has been synthesized by solvothermal reaction. The CP was fully characterized by IR spectroscopy, elemental analysis, thermogravimetric analysis, and powder and single-crystal X-ray diffraction. It presents a three-dimensional (3D) structure based on tetranuclear CoII secondary building units (SBUs) with a tfz-d net and point symbol (43)2(46·618·84). The 4-(2,4-dicarboxyphenoxy)phthalic acid (H4dcppa) ligands are completely deprotonated and link {Co4(COO)4}4− SBUs into two-dimensional (2D) layers. Furthermore, adjacent layers are connected by 1,4-bis(1H-imidazol-1-yl)benzene (bib) ligands, giving rise to a 3D supramolecular architecture. Interestingly, there are numerous elliptical cavities in the CP where isolated unique discrete hexameric water clusters have been observed. The results of thermogravimetric and magnetic analyses are described in detail.

The coordination polymer, namely, [Cd (L)2(phen)]n (1) (HL=2,4-dinitro-benzoic acid, phen=1,10-phenanthroline) has been hydrothermally synthesized. Compound 1 was structurally characterized by IR spectra, thermogravimetric analysis and single-crystal X-ray diffractions. The carboxylate groups of L- adopt the bridging monodentate and bidentate modes to link two Cd2+ ions, resulting in a 1-D zigzag chain structure. The solid state photoluminescent property of 1 has been investigated at room temperature.
