摘    要:用水热法培养出3-(吡啶-4-基)-5-(1H-1,2,4-三唑-3-基)-1,2,4-三唑(简写成PYTZ)的晶体及其与过渡金属Co(Ⅱ)的配合物晶体:PYTZ · H2O (1)、Co(PYTZ)2(H2O)2]·4H2O (2),并通过X射线单晶衍射、元素分析、红外光谱、热重分析对其进行了表征。晶体结构表明,晶体1属于单斜晶系,P2(1)/c空间群;配合物晶体2属于单斜晶系,P2(1)/c空间群。配合物2中Co (Ⅱ)离子六配位呈八面体构型,N-H?O、O-H?N和O-H?O氢键将单个分子连接成二维超分子网络结构,并对其热分解过程进行了研究。

关 键 词:水热法  3-(吡啶-4-基)-5-(1H-1  2  4-三唑-3-基)-1  2  4-三唑  钴配合物  晶体结构

Abstract:The crystal of 3-(pyrid-4-yl)-5-(1H-1 ,2 ,4-triazol-3-yl)-1 ,2 ,4-triazole(PYTZ) and its Co(Ⅱ) complex were synthesized through hydrothermal method ,they were PYTZ · H2O(1),Co(PYTZ)2 (H2O)2]·4H2O(2).Theywerestructurallycharacterizedbyelementalanalysis ,thermalstabilityanaly-sis ,IR and single-crystal X-ray diffraction analysis .Crystal structural analysis reveals that both crystal 1 and 2 crystallizes in monoclinic system ,space group P2(1)/c .In complex 2 ,the Co(Ⅱ) was six-coordina-ted forming octahedron coordination environment .Moreover ,N- H?O ,O- H?N and O- H?O hydro-gen bonds in complex 2 result in 2D supramolecular network and its thermal decomposition process was also studied .
Keywords:hydrothermal method  3-(pyrid-4-yl)-5-(1H-1  2  4-triazol-3-yl)-1  2  4-triazole  Co(Ⅱ) com-plex  crystal structure
