“…Cagelike metallasilsesquioxanes (CLMSs) constitute a wide family of metallacomplexes, providing an impressive variety of nuclearities as well as types of molecular architectures. − These factors logically endow CLMSs with an impressive list of functions and potential applications. Among these, CLMSs’ derivatives were investigated in the design of molecular magnets (including examples of single-molecule magnet or spin glass behaviors) − and objects with photophysical properties (e.g., CLMS-based luminescent thermometers). − In turn, several functional coordination polymers, − ceramics, , anodes, , fungicides, and flame retardants were successfully developed on the basis of CLMSs. CLMSs are widely applied as homo- and heterogeneous catalysts as well as components of catalytic systems. ,− Among recent reports, CLMSs’ activity in (i) deacetalization/deketalization-Knoevenagel reactions, (ii) Chan–Evans–Lam couplings, (iii) Baeyer–Villiger reactions, (iv) CO 2 valorization, , and (v) carboxylations should be mentioned.…”

The study describes a new feature in the self-assembly of cagelike manganese-based phenylsilsesquioxanes consisting of the strong influence of acetone solvates on the formation of a cage structure. By this convenient approach, a series of new tri and tetra manganese-based silsesquioxane complexes with (i) 1,10-phenanthroline, (ii) pyrazine, or (iii) 3,5-dimethylpyrazole (dmpzH) ligands were isolated and characterized. Single-crystal X-ray diffraction studies established the molecular architectures of all of the synthesized products. Several compounds represent extraordinary types of cagelike metallasilsesquioxane (CLMS) molecular architectures. Pyrazine- and dmpzH-based Mn3Na3 compounds exhibit total oxidation of initial Mn(II) ions to the Mn(III) state. They present relatively weak antiferromagnetic interactions between the manganese centers. The catalytic performance of a representative precatalyst Mn–CLMS compound, [(Ph6Si6O12)2Mn3Na3(dmpzH)3(acetone)3(H2O)], was investigated for the microwave-assisted oxidation of toluene to obtain benzaldehyde, benzyl alcohol, and benzoic acid as the main products. The effects of reaction parameters were studied, and under optimized conditions, using the t BuOOH oxidant, the oxygenated products were formed with a total yield of 54%, under microwave irradiation at 100 °C after 6 h, with 70% selectivity toward the formation of benzoic acid.

“…Coordination polymers, which are generated via the coordination of metal atoms and organic bridging ligands, are formed as one-dimensional (1D) chains, two-dimensional (2D) layers, or three-dimensional (3D) frames. Coordination polymers have been of great interest to researchers for years as it has various application areas such as drug transport, − luminescence, , magnetism, − gas adsorption and separation, − dye degradation, and adsorption. − Although coordination polymers are pure and relatively easy to obtain by the crystallization method, their final structures, topologies, and coordination geometries; it is significantly affected by various parameters such as solvent used in the synthesis, pH of the environment, temperature, counterions, and weak interactions. Therefore, the structure of the synthesized complexes is not usually a predicted structure.…”

2D Zinc(II)-Coordination Polymer Based on 1,3,5-Benzenetricarboxylate and Novel 4,4′-Bis((2-isopropyl-1H-imidazole-1-yl)methyl)-1,1′-biphenyl Ligands for the Adsorption of Methyl Orange

A novel 2D coordination polymer with the formula {[bisopibiphenH2][Zn2(btc)2(H2O)2]} n (complex 1) was produced via the solvothermal interaction of benzene-1,3,5-tricarboxylic acid (H3btc) ligand, novel 4,4′-bis((2-isopropyl-1H-imidazole-1-yl)methyl)-1,1′-biphenyl (bisopibiphen) compound, and Zn(II) ion. The structure of the final complex was elucidated by single crystal/powder X-ray diffraction methods (SCXRD/PXRD), scanning electron microscopy–energy dispersive spectroscopy, Fourier transform infrared spectroscopy, and elemental analysis. According to the results obtained from the SCXRD method of the complex, it was determined that the 2D complex was formed by Zn(II) central atoms with a distorted tetrahedral geometry and btc3– ligand. The novel bisopibiphen compound used was protonated and acted as a countercation within the asymmetric unit, thus forming the 3D supramolecular structure because of interactions between the 2D layers. Additionally, the topological and thermal characteristics of the complex were examined. In a later stage, the adsorption performance of complex 1 for methyl orange (MO) dye was examined along with the influence of various parameters. Kinetic and isotherm studies were also conducted to explain the nature of the MO adsorption process nature. According to this, the experimental data were well-matched by the pseudo-second order kinetics and Langmuir isotherm model. The maximum adsorption capacity of complex 1 was determined as 735.89 mg g–1 at 20 °C and pH 4.0. These findings indicated that complex 1 could be used as a promising effective adsorbent for MO adsorption from aqueous solutions.

This review highlights the most recent applications of Cd(II)-carboxylate-based coordination polymers (Cd(II)-CBCPs), such as sensors, catalysts, and storage materials, in comparison with those of Zn(II) counterparts. A wide range of species with luminescence properties were designed by using proper organic fluorophores, especially a carboxylate bridging ligand combined with an ancillary N-donor species, both with a rigid structure. These characteristics, combined with the arrangement in Cd(II)-CBCPs’ structure and the intermolecular interaction, enable the sensing behavior of a plethora of various inorganic and organic pollutants. In addition, the Lewis acid behavior of Cd(II) was investigated either in developing valuable heterogeneous catalysts in acetalization, cyanosilylation, Henry or Strecker reactions, Knoevenagel condensation, or dyes or drug elimination from wastewater through photocatalysis. Furthermore, the pores structure of such derivatives induced the ability of some species to store gases or toxic dyes. Applications such as in herbicides, antibacterials, and electronic devices are also described together with their ability to generate nano-CdO species.
