使用Demko-Sharpies方法,在溶剂热条件下可以安全、有效地获得含四唑基团的配体.基于此反应,引入叠氮短桥共配.获得了2个结构新颖的配位聚合物Co3(3-ptz)4(N3)2(H2O)2·4H2O(1)与Mn3(3-ptz)2(N3)4(H2O)·0.5H2O(2).2个配合物中,通过反应获得的桥连配体3-(pyridinyl)tetrazole(3-ptz)阴离子与过量的叠氮作为短桥参与,均采取了多种配位模式.使得化合物具有复杂的结构.同时,四唑阴离子和叠氮均传递磁耦合作用.%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 1 D 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.
