In principle, such af eature could be used also to induce the selectiveb reaking of certain bonds in solids to obtain new materials. Such ah ypothesis is demonstrated in this study for transition metal nitroprussides, where 2D solids are obtained from 3D frameworks by selective rupture of axial bonds. This contribution discusses the mechanism involved in such molecular manufacture.

The experimental information was complemented with calculations for the molecule configuration in its non-activated and activated forms.

Among the recent developments in metal-organic frameworks (MOFs), porous layered coordination polymers (CPs) have garnered attention due to their modular nature and tunable structures. These factors enable a number of properties and applications, including gas and guest sorption, storage and separation of gases and small molecules, catalysis, luminescence, sensing, magnetism, and energy storage and conversion. Among MOFs, two-dimensional (2D) compounds are also known as 2D CPs or 2D MOFs. Since the discovery of graphene in 2004, 2D materials have also been widely studied. Several 2D MOFs are suitable for exfoliation as ultrathin nanosheets similar to graphene and other 2D materials, making these layered structures useful and unique for various technological applications. Furthermore, these layered structures have fascinating topological networks and entanglements. This review provides an overview of different aspects of 2D MOF layered architectures such as topology, interpenetration, structural transformations, properties, and applications.

“…A tremendous diversity of divalent copper coordination polymer structures has been accessed by taking advantage of this ion's flexible coordination preferences, for example octahedral, square pyramidal, trigonal bipyramidal and intermediate geometries. Recent experiments have shown the utility of divalent copper‐based coordination polymers in various heterogeneous catalytic schemes, from allylation of organic aldehydes to toxic dye degradations in aqueous suspension . In comparison to the plethora of previously reported coordination polymers based on the isomeric benzenedicarboxylate ligands mentioned above, there have been far fewer reports of mixed‐ligand coordination polymers containing the 2‐(carboxymethoxy)benzoate ligand (2‐mcob, Scheme ), which has a flexible ether‐containing carboxylate moiety ortho to a rigid carboxylate arm .…”

Copper coordination complexes containing the 2‐methoxycarboxybenzoate (2‐mcob) ligand show different topologies depending on the nature of the dipyridyl coligand. [Cu2(2‐mcob)2(ebin)]n (1) [ebin = ethanebis(isonicotinamide)] shows a ladder structure based on anti‐syn bridged [Cu(OCO)]n chain motifs. [Cu2(2‐mcob)2(bbin)(H2O)2] (2) [bbin = butanebis(isonicotinamide)] displays a dimeric molecular structure. [Cu2(2‐mcob)2(hbin)]n (3) [hbin = hexanebis(isonicotinamide)] manifests a ladder structure very similar to that of 1. {[Cu(2‐mcob)(dpa)]·H2O}n (4) [dpa = bis(4‐pyridyl)amine] shows a chain coordination polymer structure. All four materials showed significant promise as heterogeneous degradation catalysts for Congo Red dye in aqueous suspension under ultraviolet irradiation. Variable temperature magnetic susceptibility experiments for 1 indicated the presence of weak antiferromagnetic exchange (g = 2.059(2), J = –0.84(2) cm–1). Thermal degradation behavior is also discussed.
