【摘要】 以1-氢-1,2,3-三氮唑-4,5-二甲酸为配体合成了1个六核钴配合物,[Co6(TDA)4(H2O)14]·5H2O(1)(H3TDA=1H-1,2,3-triazole-4,5-dicarboxylic acid)。对其进行了红外光谱、元素分析、热重分析、X-射线单晶和粉末衍射表征。晶体结构分析表明该配合物属于正交晶系,P21212空间群,晶胞参数:a=1.647 30(2)nm,b=1.653 30(2)nm,c=0.726 90(10)nm,Flack参数为0.00(13)。配合物中6个钴离子通过4个1-氢-1,2,3-三氮唑-4,5-二甲酸桥联成1个六核钴单元,六核钴单元之间进一步通过氢键连成三维超分子结构。磁性测试表明钴离子之间存在反铁磁相互作用。更多还原

【Abstract】 A new hexanuclear CoⅡcomplex, namely [Co6(TDA)4(H2 O)14 ]·5H2 O(1)(H3 TDA=1H-1,2,3-triazole-4,5-dicarboxylic acid), has been successfully synthesized and characterized by infrared spectra, elemental analysis, thermogravimetric analysis, powder and single-crystal X-ray diffraction. Complex 1 crystallizes in orthorhombic space group P21 21 2, with cell parameters: a=1.647 30(2) nm, b=1.653 30(2) nm, c=0.7326 90(10) nm and Flack parameter of 0.00(13). In title complex, six CoⅡions are connected by four TDA3-ligands to form a hexanuclear CoIIunit, which can be extended to a 3D supramolecular architecture through the hydrogen-bonding interactions. Magnetic study reveals the dominant antiferromagnetic interaction exist between CoⅡions in 1. CCDC: 930110.更多还原
