摘要: 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。

Abstract: 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.
