| Popis: | Two new coordination polymers, [Ag(tza)]{sub {infinity}} (1) (Htza=tetrazole-1-acetic acid) and [Cu(tza){sub 2}]{sub {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{center_dot}{center_dot}{center_dot}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{sub 4}(tza){sub 4}] as subunits with the weak ferromagnetic interactions between Cu(II) ions, which are further stabilized by inter-lamellar C-H{center_dot}{center_dot}{center_dot}O hydrogen bonds in the resulting 3-D supramolecular framework. - Graphical abstract: Two novel coordination polymers, [Ag(tza)]{sub {infinity}} (1) and [Cu(tza){sub 2{infinity}} (2) have been prepared and characterized.
