Two sinusoidal wavelike 2D coordination polymers with benzophenone-4,4′-dicarboxylate

Three new isostructural manganese coordination polymers, [Mn(H 2 O)(bpdc)] (1), [Mn(DMF)(bpdc)] (2), and [Mn-(DMSO)(bpdc)] (3) (bpdc = benzophenone-4,4′-dicarboxylate), have been successfully crystallized employing solvent variation. A single crystal X-ray diffraction study revealed that the three solids built of manganese polyhedron (square pyramidal in 1 and octahedral in 2 and 3) extended into two-dimensional sheets through manganese carboxylate coordination interaction. The packing of the layers, however, was greatly influenced through hydrogen bonding exerted by the coordinated solvent molecules (H 2 O, DMF, and DMSO) occupying the apical position of the manganese polyhedron. Low-temperature antiferromagnetic interactions arising due to coupling between the adjacent Mn 2+ ions showed a strong correlation with the variation in the packing of the layers. First-principles calculations of the electronic structures of the solids in terms of singlet (S = 0 with Noodleman's Broken Symmetry) and triplet (S = 1) states showed the superexchange interaction energies to be −0.24, −0.12, and −0.18 eV, respectively, for 1, 2, and 3; the magnetic exchange coupling variation is in correspondence with the decrease in H-bonding interaction holding the layers: H 2 O < DMSO < DMF. The paper also postulates a mechanistic pathway for the observed crystal packing in terms of supramolecular condensation of 1:1 manganese dicarboxylate complexes through a combination of coordination and H-bonding interactions.

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.
