“…Metal orotates have also caught growing acknowledgement in medicine. As a part of our continuing research on crystal engineering of metal-organic/orotate crystals comprising synthon induced molecular accumulation into higher dimensionality [29][30][31][32][33][34][35] in this manuscript we have reported 3D hydrogen bonded Zn-orotate network based upon potassium orotate, in which carboxylic group will be available to be coordinated to metal ion and imino and carbonyl oxygen will provides platform for non-covalent interactions (N-H···O and O-H···O synthons). Since the carbonyl group and carboxylate anion is a universal H-bond acceptor simultaneously as imino group is an H-bond donor, these peripheral groups are anticipated to interact with each other or with aqua ligand through hydrogen bonding, of pyrimidyl ring (Scheme 1).…”

Orotic acid formulated coordination network of formula [Zn(HOr)·3H 2 O] n (1) prepared by reactions of orotic acid potassium salt [K(H 2 Or)] accompanied by metal salts Zn(OAc) 2 ·2H 2 O at room temperature. X-ray single-crystal investigation confirms that the carbonyl oxygen of the ring in 1 is structure factor for 1D Zn-orotate coordination chain. The hydrogen bonding among uncoordinated carboxylate oxygen of ligand and one of the aqua ligand assembles the nearby parallelly stacked 1D coordination chain into 2D hydrogen bonded architecture, further hydrogen bonding among coordinated water and carbonyl oxygen incorporating O-H···O synthons yielding into 3D hydrogen bonded coordination network. O-H···O synthons were the only concoction for hydrogen bonded metal-organic network of zinc coordination polymers. The emission spectra of Zn-orotate complex shows excitation wavelength at 270 nm which depicts that 1 has strengthened photoluminescence with peak recorded of 376 nm (3.2975 eV) and is the outcomes of n-π* and π-π* transitions of orotate ligand. Thermal decomposition predicts that at 120 °C, lattice water molecule entirely release out from the complex, moderately degradation starts and around 370 °C the entire disintegration has been inspected.

“…Interestingly, Zn-SBF-2 complex displays similar rows with alternating monodentate and bidentate carboxylates along both the directions of the grid, while Zn-SBF-3 complex shows two different rows, one with only bidentate and the other with only monodentate carboxylates along two directions of the grid. Many other sql nets have been given in the literature. − …”

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.

“…Metal–organic frameworks (MOFs) have been exploited in a wide range of research sectors due to their varied network topologies and potential applications such as magnetism, − gas adsorption, , separation, , luminescence, − drug delivery, adsorption, − photocatalysis, , heterogeneous catalysis, , and so on. The key parameter used to identify the MOFs is the number of used organic linkers and inorganic secondary building units (metal nodes). − The attractive properties, structural features, and intriguing topologies are coupled with high surface area, porosity, and thermal stability. , MOFs comprising the mixed ligands polycarboxylate and N-donor linkers are also employed among the functional organic ligands to enhance the dimensionality of the structure. − It is still a difficult task, however, because a variety of delicate factors, including metal nodes, organic linkers, temperatures, solvents, and pH values, may significantly influence the final architectures of the MOFs. − …”
