| 摘要: 分别以E-3-[4-(羧甲氧基)-苯基]丙烯酸(H2L1)和E-3-[3-(羧甲氧基)-苯基]丙烯酸(H2L2)为主配体，合成了3种钴(Ⅱ)配位聚合物：[Co(L1)(bpp)]n(1)，{[Co(μ3-OH)2(L2)4(bpy)2(H2O)4]·12H2O}n(2)和[Co(L2)(bpy)]n(3)(bpp：1，3-二吡啶基丙烷，bpy：4，4-联吡啶)。通过元素分析、红外光谱、X射线粉末和单晶衍射对其进行了结构表征。结果表明钴(Ⅱ)离子在这3种配合物中具有不同的配位环境，导致3种配合物具有不同的晶体结构和磁性特征。 | |

| Abstract: Three Co(Ⅱ) complexes based on E-3-[3-(carboxymethoxy)-phenyl]acrylic acid (H2L1) or E-3-[3-(carboxymethoxy)-phenyl]acrylic acid (H2L2), namely [Co(L1)(bpp)]n(1), {[Co(μ3-OH)2(L2)4(bpy)2(H2O)4]·12H2O}n (2), and [Co(L2)(bpy)]n(3) (bpp: 1,3-bi(pyridin-4-yl)propane, bpy: 4,4-bipyridine), were synthesized and characterized by elemental analysis, IR, XRPD and X-ray single-crystal structure analysis. Different coordination environment for Co(Ⅱ) ions and thereby different crystal structures and magnetism were observed for these three complexes. The magnetic properties of complexes 1 and 2 were discussed in detail. | |
