| 中文摘要: |
| 在水热条件下，以4, 5-咪唑二羧酸作为有机配体，1, 10-邻菲罗啉作为端基配体，硝酸钴作为金属源，合成了一维超分子化合物[Co5(C5N2O4H)4(C5N2O4H3)2(C12N2H8)4(H2O)2]?(H2O)6 (1)。单晶X-射线衍射分析结果表明，化合物1属于三斜晶系，P-1空间群，Mr = 2082.09，a = 13.104(3) ?，b = 13.463(3) ?，c = 13.708(3) ?，α = 75.03(3)°，β = 70.00(3)°，γ = 65.39(3)°，V = 2046.9 (10) ?3。在化合物1中，CoIII4四边形构筑块与CoII八面体构筑块之间通过氢键作用相互连接，沿[1 1 1]方向形成一条无限延伸的超分子链。此外，通过粉末X-射线衍射(PXRD)、热重分析(TGA)、红外光谱(IR)和CHN元素分析对化合物1进行了相关表征。 |
| 英文摘要: |
| A one-dimension supermolecular coordination polymer was synthesized by using 4, 5-imidazoledicarboxylic acid as organic ligands and Co(NO3)2?6H2O as metal ions under hydrothermal condition [Co5(C5N2O4H)4(C5N2O4H3)2(C12N2H8)4(H2O)2]?(H2O)6 (1). Single-crystal X-ray analysis reveals that compound 1 crystallizes in the Triclinic system, P-1 space group with Mr = 2082.09, a = 13.104(3) ?, b = 13.463(3) ?, c = 13.708(3) ?, α = 75.03(3)o, β = 70.00(3)°, γ = 65.39(3)° and V = 2046.9 (10) ?3. In compound 1, Co III4 squares and Co II octahedral units are connected with each other via strong hydrogen bonds interactions to construct a one-dimension supermolecular structure. CCDC: 977802. Compound 1 was also characterized by powder X-ray diffraction (PXRD), thermal gravimetric analyses (TGA), infrared spectra (IR) and CHN elemental analyses. |
