Synthesis, characterization and properties of some metal(II) 5-(nicotinamido)isophthalate complexes
摘要:
Four new complexes, {[M(NAIP)(H2O)(4)]center dot 2H(2)O}(n) (M = Co (1), M = Mn (2)). {[Zn(NAIP)]center dot 0.5H(2)O}(n) (3) and {Cd(NAIP)(H2O)(2)]center dot 1.5H(2)O}(n) (4) [H(2)NAIP = 5-(nicotinamido)-isophthalic acid] have been prepared and structurally characterized. The ligand NAIP(2-) exhibits different coordination modes and leads to the formation of various architectures. Complexes 1 and 2 show a one-dimensional (1D) zigzag chain, where hydrogen-bonding interactions further link these chains to a three dimensional (3D) supramolecular structure. For complex 3, a 3D coordination network with a four-coordinated Zn(II) and NAIP(2-) as a SBU was observed. Complex 4 presents a three-connected 2-fold interpenetrated 3D network with a (10, 3)-b net topology. Their luminescent and magnetic properties have been investigated in the solid state.

沙漏状多孔金属有机框架LIFM-12 ,构建在具有Cu 2+桨轮簇的T形柔性配体上,在可逆分子客体结合时显示出温度和气体吸附响应的结构动力学。温度依赖性单晶和粉末X射线衍射实验表明,具有适应性行为的框架的开门状态有利于气体分子的动力学扩散,导致不同尺寸的孔隙顺序填充,从而产生让人想起观察到的呼吸行为吸附等温线的几个步骤。此外,吸附研究表明, LIFM-12对 CO 2相对于轻质气体 N 2 、CH 4和 CO 的吸附选择性为 10-25,对于 C 3 H 6相对于CH 4 的吸附选择性高达 200。

An hourglass porous metal–organic framework, LIFM-12, constructed on a T-shaped flexible ligand with Cu2+ paddle-wheel clusters, shows temperature and gas adsorption responsive structural dynamics upon reversible molecular guest binding. Temperature-dependent single crystal and powder X-ray diffraction experiments show that the open gate status of the framework with adaptive behaviours facilitates
