An Unprecedented 3D Self-catenated Four-coordinated Dense Net of Silver-Organic Framework

Abstract

The rational design and synthesis of novel coordination polymers (CPs) or metal-organic frameworks (MOFs) is of great interest in modern inorganic chemistry not only for their potential applications as functional materials in fields such as gas storage, luminescence, catalysis, ion exchange, and so on, but also for their intriguing variety of topologies. 1In particular, topology focuses on the network connectivity generated via the reduction of periodic nets into node-andlinker/vertex-and-edge representations, which helps greatly the understanding of structural complexity, variety and entanglements of the coordination architectures.2,3 It is no doubt that the discovery of artificial MOFs with predicted subnet topologies is of great significance in understanding supernet-subnet relations based on the knowledge of the chemical properties of the components (metals and ligands). Therefore, tiny variation of nodes may generate huge differences on topologies since the network topology is reflected by the symmetry of nodes and nature of edges. 2gFrom both zeolite chemistry and crystal engineering points of view, the nets built from 4-coordinated (4-c) centers capture much attention both for their inherent interest (all zeolites are 4-c nets) and from a theoretical point of view: many 4-c nets have been deduced and summarized firstly by Wells 2a followed by several comprehensive discussions.

Syntheses, Structures, and Luminescence Properties of Two Copper(II) Complexes Constructed by Rigid Bis(triazole) and Nitrogen‐containing Carboxylic Acid Ligands

“…Therefore, research studies using rigid bis(triazole) ligands in the assembly of new complexes have become significant. The multifunctional carboxylate ligands with nitrogen‐bearing heterocyclic compounds have been used expansively in synthetic strategies to develop multidimensional (zero, one, two, and three dimensional) structures because of the diversity of the coordination modes and high structural stability . In this work, mixed‐ligand synthetic strategy has been applied to prepare two of copper(II)‐based complexes by designing or selecting the suitable above neutral N ‐donor ligands and polycarboxylates.…”

Assembly and Catalytic Properties of a 3D (4,6)-connected Cobalt-organic Framework with fsh Topology

“…Therefore, significant interest has arisen in the structural tuning of coordination polymers via rational selection of with N and/ or O-donors as coordination sites in the construction of crystalline materials with the three-dimensional (3D) CPs, such as pcu, msw, mok, dia, srs, cds, rtl, etc. [8][9][10][11][12][13][14][15][16][17][18] However, there is an unfavorable lack of research about the higherdimensional networks with the mixed nodes, such as (3,6)-, (4,6)-, (4,8)-, (4,10)-, and (4,12)-connected networks, which are considered to be much more difficult to obtain these networks. …”
