Temperature-tuned topologies and interpenetrations of two 3D porous copper(II)-organic frameworks and gas adsorption behaviors

Influence of the Metal Ion on the Topology and Interpenetration of Pyridylvinyl(benzoate) Based Metal–Organic Frameworks

“…Although the structure of 2 has been previously reported, 37 herein we give a description of its structure for further comparison with compounds 1, 3, and 4. Additionally, a structure very similar to 1 has been described in the literature, 38 but even though they present the same crystallographic parameters, compound 1 has one disordered guest dmf molecule in the asymmetric unit in contrast to the absence of solvent molecules on the previously reported structure. Compounds 1−4 were obtained using different conditions than that described in the literature for similar systems; however, compounds 1 and 2 presented the same structural topology of those already reported.…”

“…Compounds 1 – 4 were obtained using different conditions than that described in the literature for similar systems; however, compounds 1 and 2 presented the same structural topology of those already reported. This point should be highlighted since a correlation between the structural topology and the temperature of the solvothermal process was established in a previous paper by Xiong and co-workers . In this work, different types of structural topologies were obtained using the same conditions, only differing on the metal ion.…”

“…This point should be highlighted since a correlation between the structural topology and the temperature of the solvothermal process was established in a previous paper by Xiong and coworkers. 38 In this work, different types of structural topologies were obtained using the same conditions, only differing on the metal ion. Such an approach is highlighted in Scheme 1, with compound 1 presenting a 5-fold interpenetrated lvt framework, while the isomorphous compounds 2 and 3 exhibit a 7-fold interpenetrated dia framework, and finally, compound If we consider the long Cu1−O2 bond length, the carboxylate moieties are coordinated in a bidentate fashion, giving rise to a highly distorted hexacoordinated environment around the copper ions.…”

Structural and Magnetic Properties of a Pyridyl(vinyl)benzoate-Based Metal–Organic Framework with Iron(II) as Spin Carrier

“…Considering the structures deposited in the CCDC database, a survey of 41 structures with this ligand shows an average angle of 17.7°, ranging from a maximum of 53.3° to a minimum of 0°. In contrast with the roughly planar structure of the pvb – ligand (or its derivative, disregarding the carboxylate group in both cases), in other coordination compounds, − ,, the pvb – structure in 1 is highly distorted, as noted by the presence of a twist angle between the pyridyl ring and the aromatic ring of the benzoic moiety of 37.85° and 67.61° for each pvb – anion in the asymmetric unit, respectively (Figure S5).…”

“…Concerning the functionalization of carboxylate derivatives, the pyridylvinyl­(benzoate) derivatives constitute good candidates for the formation of extended molecular structures due to their coordination sites at opposite sides. ,, In addition, variations of the experimental conditions, like temperature, nature of the metal ion, and solvent molecules can lead to pyridylvinyl­(benzoate) CPs with distinct topologies. − Thus, taking advantage of the use of pyridylvinyl­(benzoate) as bridging ligand, hydroxo as a coligand, iron­(II) ions as spin carriers, and appropriate hydro­(solvo)­thermal conditions, MOFs with interesting magnetic properties can be obtained.…”
