Abstract

The reaction of 5-nitroisophthalic acid (H(2)NIA) with Gd(NO(3))(3)·6H(2)O in DMF afforded three new metal-organic frameworks: [Gd(NIA)(1.5)(DMF)(2)]·DMF (I), [Gd(2)(NIA)(3)(DMF)(4)]·xH(2)O (II) and [Gd(4)(NIA)(6)(DMF)(5.5)(H(2)O)(3)]·4DMF·H(2)O (III). These compounds can be prepared through a variety of methods. Compounds (I) and (II) are more reproducibly formed than compound (III). Network analysis revealed (I) to have a (4(12).6(3))-pcu topology, while (II) displays a (4(2).8(4))(4(2).8(4))-pts topology. Compound (III) was found to present the uncommon 4,5,6T11 topological net, which combines aspects of both the pcu and pts topologies. The short symbol of this net is (4(4).6(2))(4(6).6(4))(2)(4(8).6(6).8).

GdIII和5-硝基间苯二甲酸三种相关金属有机骨架的拓扑结构研究。

5-硝基间苯二甲酸(H(2)NIA)在DMF中与Gd(NO(3))(3)·6H(2)O反应生成了三种新的金属有机骨架:[Gd(NIA)(1.5)(DMF)(2)]·DMF (I)， [Gd(2)(NIA)(3)(DMF)(4)]·xH(2)O (II)和[Gd(4)(NIA)(6)(DMF)(5.5)(H(2)O)(3)]·4DMF·H(2)O (III)。这些化合物可以通过多种方法制备。化合物(I)和(II)的形成比化合物(III)更具可重复性。网络分析显示(I)具有(4(12).6(3))-pcu拓扑结构，而(II)具有(4(2).8(4))(4(2).8(4))-pts拓扑结构。化合物(III)呈现罕见的4,5,6t11拓扑网络，它结合了pcu和pts拓扑的各个方面。简短的净的标志是(4(4)6(2))(4(6)6(4))(2)(4)(8)6(6)。8)。

期刊介绍： Acta Crystallographica Section B: Structural Science, Crystal Engineering and Materials publishes scientific articles related to the structural science of compounds and materials in the widest sense. Knowledge of the arrangements of atoms, including their temporal variations and dependencies on temperature and pressure, is often the key to understanding physical and chemical phenomena and is crucial for the design of new materials and supramolecular devices. Acta Crystallographica B is the forum for the publication of such contributions. Scientific developments based on experimental studies as well as those based on theoretical approaches, including crystal-structure prediction, structure-property relations and the use of databases of crystal structures, are published.
