Two new coordination polymers, [Ag(tza)](infinity) (1) (Htza = tetrazole-1-acetic acid) and (Cu(tza)(2)](infinity) (2) have been prepared at room temperature and characterized by X-ray crystallography, IR, UV-vis, fluorescence spectra and magnetism analysis. Compound 1 exhibits extended helical chains through bridging ligand tza. The Ag...Ag interactions between the adjacent chains form a 3-D framework featuring the extended tza-connected Ag chains that obviously affect the photoluminescent property. Compound 2 features undulated layered structure with hourglass-shaped [Cu-4(tza)(4)] as subunits with the weak ferromagnetic interactions between Cu(II) ions, which are further stabilized by inter-lamellar C-H...O hydrogen bonds in the resulting 3-D supramolecular framework.
