| Abstract: The Demko-Sharpless′ is a very effective method for synthesis of the tetrazole compounds. Using this method, two coordination polymers have been obtained using solvent thermal reactions, and characterized structurally and magnetically. The 2D layer 1, Co3(3-ptz)4(N3)2(H2O)2·4H2O is consisted of 1D azido-bridged Co2+ chains linked through the coordinated Co2+ building block. The 3D network 2, Mn3(3-ptz)2(N3)4(H2O)·0.5H2O is consisted with complicated 2D azido-bridged Mn2+ layers pillared by bridge ligands. The excessive azide ions in the reaction adopt μ-1,1, μ-1,3 modes in 1 and μ-1,1, μ-1,3, μ-1,1,3 modes in 2, bridge the neighboring metal ions and transmit magnetic couplings. The 3-(pyridinyl)tetrazole anion, which is the production of the Demko-Sharpless′ reaction, bridges with bidentate and tridentate mode in 1, with tridentate and pentadentate mode in 2. They not only bridge the metal ions, but also transmit magnetic couplings along with azide ions. CCDC: 687278, 1; 687279, 2. |
