5-氨基双四唑富氮配位化合物的合成、结构及其对高氯酸铵的热分解影响

水热条件下合成了两个5-氨基双四唑配位化合物Cu(bta)(bpy)(H2O)(1)和Pb2(bta)2(en)2.4H2O(2)(H2bta=5-氨基双四唑,bpy=2,2′-联吡啶,en=乙二胺),并借助单晶X-射线衍射技术对其结构进行了表征。在配合物1中,5-氨基双四唑配体以双齿螯合模式与铜离子配位形成离散的分子,并通过H键作用进一步形成了三维的超分子结构。在配合物2中,强的R22(8)氢键环作用将双核的Pb2(bta)2(en)2单元连接成一维的链,这些链通过与水分子氢键作用被进一步组装成三维的超分子结构。另外,通过DSC技术探究了它们作为添加剂对高氯酸铵的热分解催化影响。研究发现,铅基化合物2的催化效果较铜基化合物1要好。

Nitrogen-Rich Coordination Compounds with N,N-Bis(1H-tetrazole-5-yl)-amine: Synthesis, Structure and Effect on the Thermal Decomposition of Ammonium Perchlorate

Two coordination compounds with N,N-bis(1H-tetrazole-5-yl)-amine(H2bta),Cu(bta)(bpy)(H2O)(1) and Pb2(bta)2(en)2·4H2O(2)(bpy=2,2′-bipyridyl and en=ethylenediamine),have been hydrothermally synthesized and structurally characterized by single crystal X-ray diffraction.In 1,the H2bta ligands coordinate with Cu2+ ions in the bidentate chelate mode to form discrete molecular structures,which are assembled through extended hydrogen bonds to generate a 3D architecture.2 presents a 3D supramolecule stucture constructed from 1D chains,in which the binuclear Pb2(bta)2(en)2 units are bridged by the strong hydrogen bond ring motif R22(8).Furthermore,compounds 1 and 2 were explored as additives to promote the thermal decomposition of ammonium perchlorate(AP) by the differential scanning calorimetry techniques(DSC).DSC curves reveal that lead-based compound 2 shows better performance than the copper-based compound 1.CCDC: 855627,1;774052,2.
