Solvothermal reactions of Cd(OAc)2·2H2O with 2,2′-azodibenzoic acid and five positional isomeric N-donor bipyridyl benzene ligands in MeOH/H2O at 170 °C gave rise to five coordination polymers. Complexes 1–5 were characterized by elemental analysis, IR spectroscopy, powder X-ray diffraction, and single-crystal X-ray diffraction.

The syntheses of new silver complexes of five isomeric bis(pyridylmethyleneoxy)benzenes, differing in the position of substitution on the benzene and pyridine rings, and three isomeric 1,3,5-tris(pyridylmethyleneoxy)benzenes, differing in the position of substitution on the pyridine ring, are described. The structures of six of these complexes were characterised using X-ray crystallography, showing

Twopolymeric frameworks, [Zn(Dpb)(Oba)] n (Ι) and [Cd(Dpb)(2,6-Pda)H2O] n · nH2O (II) (Dpb = 1,4-bis(pyridin-3-ylmethoxy)benzene, H2Oba = 4,4'-oxybis(benzoic acid), 2,6-H2Pda = 2,6-pyridyl-dicarboxylate), have been hydrothermally synthesized and structurally characterized by single crystal X-ray diffraction method (CIF files CCDC 1488269 (Ι), 1488270 (II)). Complex Ι is a 2D layer structure, which
