“…Antiferromagnets frequently exhibit such spin canting, where the spin carriers are linked by monoatomic bridges . Further, the most frequently encountered magnetic properties in 2D MOFs is the antiferromagnetic ordering, and this is dominated in the Cu(II) containing 2D MOFs. − ,,− Several Mn(II) and Co(II), ,− ,− ,− and a few Fe(II) and Ni(II) 2D MOFs with mostly containing (4,4) grid structures have also exhibit this antiferromagnetic ordering. ,− ,− …”

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.

An Imidazolate‐ and Azide‐Bridged Copper(II) Coordination Polymer Consisting of Alternating Di‐ and Mononuclear Units

Using the CuII‐imidazole(Him) complex [Cu(Him)4Cl]Cl as the starting material, the imidazolate (im)‐ and azide‐bridged CuII coordination polymer [Cu3(Him)4(im)2(N3)4]n was successfully obtained. Single‐crystal X‐ray analysis revealed that it possesses an im‐bridged linear‐chain structure consisting of alternating dinuclear units with a symmetric end‐on azide‐bridged [Cu(μ1,1‐N3)2Cu]2+ core and mononuclear units. All of the Cu ions adopt a square pyramidal geometry with an azide at the Jahn–Teller elongated apical position. Some of the azides act as end‐to‐end interchain bridging ligands from the mononuclear unit to the nearest neighbouring dinuclear unit of the adjacent chain forming a two‐dimensional network. Temperature‐variable magnetic susceptibility measurements showed that it exhibits one‐dimensional ferrimagnetic‐like behaviour, which can be ascribed to two types of exchange couplings with opposite signs, namely a weak ferromagnetic coupling through the end‐on azide bridges within the dinuclear units and a stronger antiferromagnetic coupling through the im bridges between the di‐ and the mononuclear units.

Mononuclear nickel(II) complexes were prepared by reaction of the three ONNO type reduced Schiff bases bis‐N,N′‐(2‐hydroxybenzyl)‐1,3‐propanediamine (LHH2), bis‐N,N′‐(2‐hydroxybenzyl)‐2,2′‐dimethyl‐1,3‐propanediamine (LDMHH2), and bis‐N,N′‐[1‐(2‐hydroxyphenyl)ethyl]‐1,3‐propanediamine (LACHH2) with NiII ions in the presence of pseudo halides (OCN–, SCN– and N3–). The complexes were characterized with the use of elemental analyses, IR spectroscopy, and thermal analyses. The molecular structure of one of the complexes was obtained by single‐crystal X‐ray diffraction. The obtained complexes are mononuclear, and a pseudo halide molecule is attached. One of the oxygen atoms of the ligand is in phenolate and the other was in phenol form. According to the thermogravimetry results, it was thought that the pseudo halide thermally detaches from the structure as hydropseudo halide. In azide‐containing complexes an endothermic reaction was observed although the azide group usually decomposes with an exothermic reaction.
