【摘要】 本文在乙醇溶液中合成了结构为[CO（NO₃）（H₂O₅）]⁺·（NO₃^-）（18-C-6）（H₂O）的粉红色晶状配合物.用元素分析、电导测定、 紫外可见光谱、红外光谱及热分析等方法对该化合物进行了研究.并由 X-射线单晶结构分析确定,该化合物晶体属单斜晶系,空间群 p21/n.晶胞参数 a=7.258（1）,b=16.149（2）,c=20.825（3）（?）,β=99.15（3）°,V=2409.8（?）³,Z=4.结果表明.Co²⁺与5个水及一个硝酸根上的氧原子配位,形成稍有畸变的八面体配位构型.18-冠-6的氧原子未直接向钴配位,而是通过氢键与配位水相联系.更多还原

【Abstract】 This paper reports the synthesis,properties and crystal structure oftitle compound[(Co（Co（NO₃）.（H₂O）₅）]⁺.（NO₃^-）.（H₂O）.（18-c-6）.The com-pound has been studied by element analysis,conductivity determination,DSC-TG,UV and IR spectra.The structure of the single crystal has beendetermined by X-Ray diffraction.The crystal belongs to the mcncclinicsystem and the space group is P₂₁/rn with lattice parameters are a=7.258（1）,b=16.149（2）,c=20.825（3）（?）,β=99.15（3）°,V=2409.8（?）.z=4.Theresults show.Cobalt（Ⅱ）coordinates with five water molecules and anoxygen of nitrate group,and leads to the octahedral coordination confi-guration which is distorted slightly.The oxygens of 18-C-6 are not direc-tly coordinated to the Cobalt（Ⅱ）but connected to the coordinated watermolecules by hydrogen bonds.更多还原
