| 摘 要： | 以3,4-吡唑二甲酸(H3pdc)为配体分别与氯化铜、氯化镍反应,得到了2个过渡金属配合物:[M(H2pdc)2(H2O)2]·2H2O(M=Cu(1)和Ni(2)),用元素分析、红外光谱、X-单晶衍射结构分析、热重分析和荧光分析对其进行了表征。晶体结构分析表明配合物1和2均为单核结构,金属离子与来自2个H2pdc-中的2个N原子和2个羧基O原子,以及2个水分子中的2个O原子配位,形成六配位的八面体构型。配合物1和2中的独立结构单元[M(H2pdc)2(H2O)2]·2H2O通过3种分子间氢键(O-H…O,N-H…O和C-H…O)形成三维(3D)空间结构;此外我们还研究了配合物1和2的热稳定性和荧光性质。

| Abstract: | Two monomeric complexes of [M(H2pdc)2(H2O)2]·2H2O (M=Cu (1) and Ni (2)) (H3pdc=3,4-pyrazoledicarboxylic acid) were synthesized by the reaction of H3pdc with CuCl2·2H2Oand NiCl2·6H2O, respectively. The compounds were characterized by elemental analysis, IR spectra and single crystal X-ray diffraction. Single crystal analysis shows that metal ions have all octahedral geometry coordinated by two nitrogen atoms and two oxygen atoms from two H2pdc-ligands and two oxygen atoms from two coordination water moleculars. The independent componentes [M(H2pdc)2(H2O)2]·2H2O are further assembled into 3D hydrogen-bonded structure through intermolecular hydrogen bonds. The thermal and photoluminescent properties of these complexes were also investigated. CCDC: 997997, 1; 997998, 2. |
