  摘要：

  摘要 采用热重法和差热分析法，系统地研究了稀土甲酸酐在流动氮气气氛中的热分解。分解由两个或三个阶段组成 2 Ln(HCO 2 ) 3 → 2 LnO(HCO 2 ) → Ln 2 O 2 ·CO 3 → Ln 2 O 3镧甲酸。在整个系列中都观察到了碳酸氢盐。镨和钕的碳氧酸盐晶体结构为单斜晶型，其他元素为四方晶型。稀土甲酸盐的热稳定性与其结构畸变有关，这必须归因于稀土金属离子半径的收缩。镧分解为甲酸镝的第一阶段是 Avrami 型反应。钬到镥的甲酸盐在分解的主要第一阶段熔化，它们的动力学是一级反应的特征。确定了分解主要阶段的动力学参数，如活化能和指前因子。

  three‐dimensional metal–organic framework Gd(HCOO)3 is characterized by a relatively compact crystal lattice of weakly interacting Gd3+ spin centers interconnected via lightweight formate ligands, overall providing a remarkably large magnetic:non‐magnetic elemental weight ratio. The resulting magnetocaloric effect per unit volume is decidedly superior in Gd(HCOO)3 than in the best known magnetic refrigerant

  三维金属-有机骨架Gd（HCOO）3的特征在于，通过轻质的甲酸酯配体相互连接的，相互作用较弱的Gd 3+自旋中心相对较紧凑的晶格，总体上提供了很大的磁性：非磁性元素重量比。在液态氦温度和低中度应用领域，Gd（HCOO）3所产生的每单位体积的磁热效应明显优于最著名的磁性制冷剂材料。

  Ho(HCO3)3·6H2O, which are the only known bicarbonates of rare earth metals, were refuted and the published crystal structures were discussed. Because of the structural relationship of Ho(HCO3)3·6H2O to rare earth nitrate hexahydrates,[1] the synthesis of holmium nitrate hydrate was considered and the crystal structure of Ho(NO3)3·5H2O was solved by single crystal X-ray diffraction measurements. Ho(NO3)3·5H2O

  Gd(HCO3)3·5 和Ho(HCO3)3·6 是目前已知的唯一稀土金属碳酸氢盐的合成路线，并对已发表的晶体结构进行了讨论。由于Ho(HCO3)3·6 与硝酸稀土六水合物的结构关系，[1]考虑合成硝酸钬水合物，通过单晶X射线解析Ho(NO3)3·5 的晶体结构衍射测量。Ho( )3·5 被确定在三斜空间群 P1 (no. 2) 中结晶，a = 6.5680(14) A, b = 9.503(2) A, c = 10.462(2) A, α = 63.739 (14)°, β = 94.042(2)° 和 γ = 76.000(16)°。晶体结构由孤立的 [Ho(H2O)4( )3] 多面体和非配位水分子组成。它与其他稀土硝酸盐五水合物同型。

  The novel polymeric formates of general formula [(Fmd)-Ln(III)(HCOO4)(infinity), (Fmd(+) = NH2-CH+-NH2; Ln = Eu (1), Gd (2), Tb (3), Dy (4)] were synthesized through solvothermal methods in formamide solutions. The compounds are isotructural; they crystallize in the orthorhombic C222(1) chiral space group. The coordination geometry at the metal centers is square antiprismatic (coordination number eight), with each formate ligand bridging adjacent lanthanide ions. The overall negative three-dimensional (3D) framework charge is balanced by the formamidinium cations sitting inside the channels along the a axis, forming extensive N H center dot center dot center dot O hydrogen bonding with the surrounding cage. All the compounds have been characterized through single-crystal/powder X-ray diffraction, IR spectroscopy, and TG-MS analysis. Finally, their luminescence and magnetic properties have been assessed, leading remarkable emission intensities, especially for the Tb(III) compound (Phi = 0.83), with corresponding lifetime decays in the micro (Dy) and millisecond (Tb, Eu) time scale. A weak but sizable antiferromagnetic interaction has been observed for the Gd(III) derivative.
