The azide anion is a short bridging ligand that has been used extensively to construct magnetic coordination polymers, and fundamental magneto-structural correlations have been substantiated by theoretical calculations. The copper(II) coordination polymer poly[bis(μ-azido-κ2N1:N1)(μ4-homophthalato-κ4O:O′:O′′:O′′′)bis(pyridine-κN)dicopper(II)], [Cu2(C9H6O4)(N3)2(C5H5N)2]n, was synthesized from homophthalic acid (2-carboxyphenylacetic acid), pyridine and azide (N3−) by a hydrothermal reaction. Single-crystal structure analysis indicated that it features a one-dimensional chain structure which is comprised of (μ1,1-N3−)(μ-syn–syn-COO−)2- and (μ1,1-N3−)2-bridged tetranuclear CuIIunits. Magnetic measurements revealed that the compound exhibits dominant antiferromagnetic behaviour.

A chain Ni (II) coordination polymer material was prepared and characterized by elemental analysis and single-crystal X-ray diffraction. It crystallizes in monoclinic, space group C2/c with a = 1.24348(13) nm, b = 1.29477(12) nm, c = 1.51480(17) nm and Dc = 1.401 g•cm-3. The results of structural analysis indicated that each Ni (II) ion forms six-coordinated with nitrogen atoms of pyridine and thiocyanate, and the Ni (II) coordination polymer material formed one dimensional chain structure by the interaction of pyridine rings.

1D chain Ca(II) coordination polymer was synthesized and characterized by elemental analysis, molar conductance, IR and single-crystal X-ray diffraction, The results of crystal structure show that each Ca(II) ion forms eight-coordinated and the complex formed one dimensional chain structure by the oxygen atoms of carboxylate and water bridged. The antibacterial activity of the Ca(II) coordination polymer and the ligand were tested, the results show that the complex show considerable antibacterial activity against escherichia coli, bacillus subtilis and staphylococcus white.

The centrosymmetric formula unit of the title one-dimensional coordination polymer, [Mn(C7H3N2O6)2(C10H8N2)] n , which is twice the asymmetric unit, contains two MnII ions, four 3,5-dinitrobenzoate anions and two 2,2′-bipyridine ligands. The 3,5-dinitrobenzoate anions connect the MnII atoms through their O atoms, resulting in the formation of a one-dimensional chain structure.

Hydrothermal reaction of Cd(NO3)2 · 4H2O with a flexible asymmetrical bridging ligand, 4-(2- pyrazinylthiomethyl)benzoic acid (Hpztmb), at 120 °C yielded a novel one-dimensional Cd(II) coordination polymer [Cd(pztmb)2(H2O)2]n (1), which has been characterized by IR spectroscopy, elemental analysis, thermogravimetry, and X-ray crystallography. The metal-organic chain of the complex is held together with its neighbors via O-H· · ·O hydrogen bonds and face-to-face π-π interactions leading to a three-dimensional supramolecular network. Compound 1 exhibits a fluorescence emission around 396 nm
