A Unique Five‐Fold Interpenetrating Framework with the dmc Topology that is Supported by Extensive O–H···O Hydrogen Bonds

Abstract

A unique supramolecular framework, [Zn 4 (H 2 O) 2 (2,5tdc) 4 (3,3Ј-bpe) 3 ] n (1), was prepared by the self-assembly of Zn(NO 3 ) 2 ·6H 2 O, 2,5-thiophenedicarboxylic acid (2,5-H 2 tdc), and 1,2-bis(3-pyridyl)-ethene (3,3Ј-bpe) under hydrothermal conditions. The coordination network of 1 can be simplified as a (3,4)-connected dmc framework with a point symbol (4·8 2 )(4·8 5 ). The void space of a single network of 1 is filled by mutual interpenetration of four crystallographically equivalent nets, generating a fivefold interpenetrating * Prof. F.-Z.

Three new Cd(II)/Zn(II) coordination polymers assembled via dual‐ligand strategy: crystal structures and luminescent properties

“…[6][7][8] By referring a large amount of literatures about MOFs, it is found that selection of an suitable organic ligand and adopt a appropriate synthetic strategy can help us to construct the desired MOFs to some extent. [9][10][11][12] In the construction of MOFs, polycarboxylate ligands with versatile coordination modes have been widely used as the organic building blocks, [13][14][15] and the mixed-ligand strategy has been proven to be one of the most effective methods for the construction MOFs with desired structures. [16][17][18] The synergestic effect of two different ligands can help us to direct the synthesis of desired MOFs.…”
