【摘要】 以3,5-二硝基苯甲酸(3,5-Hdnbc)和吡唑(pz)为配体与Co2+和Ni 2+反应,得到了2个新的配合物[Co(3,5-dnbc)2(pz)2(H2O)2](1)和[Ni(3,5-dnbc)2(pz)4](2).用元素分析、红外光谱对其进行了表征,并用单晶X-射线衍射测定了配合物的晶体结构;配合物1和2均为单核分子,配合物1通过分子内和分子间氢键形成三维网络超分子结构,而配合物2中只存在分子内氢键.更多还原

【Abstract】 Two new complexes,[Co(3,5-dnbc)2(pz)2(H2O)2](1)and[Ni(3,5-dnbc)2(pz)4](2)were obtained by the reactions of 3,5-dinitrobenzoic acid and pyrazole as ligands with Co2+and Ni 2+ions.The two complexes were characterized by elemental analysis,IR,and their crystal structures were determined by single X-ray diffraction.Both of the two complexes are mononuclear complexes.A onedimension chain supramolecular structure is formed due to the formation of intramolecular and intermolecular hydrogen bonding interactions in complex 1,while only intramolecular hydrogen bonding interactions exist in complex 2.更多还原
