“…those found in related complexes (Divya et al, 2020). The remaining two C O groups in each ligand are involved in resonance and intermolecular hydrogen bonding (and, in the cases of C2 O3 and C3 O2, in bonding to Li2A and Li2B) and have slightly longer bond lengths: C2-O3, 1.2439 (18) Å ; C3-O2, 1.2436 (19) Å ; C5-O5, 1.2442 (18) Å and C6-O6, 1.2430 (18) Å .…”

“…The first stage starts at 92 C and ends at 172 C with a derivative peak at 146.26 C and a measured weight loss of 20.13%, which is in reasonable agreement with the loss of the seven coordinated water molecules (calculated weight loss 18.91%). The second and third stages of decomposition, occurring from 298 to 550 C, correspond to the decomposition of the cyanurate ligands with a measured total weight loss of 52.80%, leading to the formation of LiNO 3 (calculated weight loss 51.07%) (Divya et al, 2020). In the fourth decomposition stage, occurring from 550 to 662 C, LiNO 3 decomposes with a measured weight loss of 20.39% to produce Li 2 O as the final solid residue (calculated weight loss 21.67%).…”

The polymeric title complex, poly[hexa-μ-aqua-diaquatetra-μ-cyanurato-tetralithium] [Li4(C3H2N3O3)4(H2O)7] n , synthesized at room temperature from an aqueous solution of lithium hydroxide and cyanuric chloride, crystallizes in the triclinic space group P\overline{1}. There are two distinct Li+ cations in the asymmetric unit, one of which, Li1, has distorted trigonal–bipyramidal geometry and is coordinated via oxygen to two cyanurate anions occupying equatorial positions, and three water molecules, two in the axial positions and the third in an equatorial position. One of the axial water ligands and the equatorial water ligand are involved in bridging to a crystallographically equivalent Li1 cation. A centre of inversion lies between the two Li1 cations and the Li1...Li1 distance is 3.037 (5) Å. The remaining axial water ligand bridges to the second Li cation, Li2, which is disordered over two crystallographic sites with approximately equal occupancy, and has an Li1...Li2 distance of 3.438 (7) Å. The terminal Li2 cation is coordinated to three water molecules and an oxygen atom from a cyanuric anion and has a distorted tetrahedral geometry. A three-dimensional network of intermolecular hydrogen bonds involving N—H...O, O—H...O and O—H...N interactions serves to hold the structure together, as confirmed by a Hirshfeld surface analysis. The title compound was further characterized using IR and UV–vis spectroscopy and TG–DTA analysis.

“…Chemists are increasingly interested in the design and synthesis of heteropolynuclear complexes of d and s-block elements owing to original structures with interesting properties in various fields such as magnetism [1,2], catalysis [3,4] and luminescence [5]. The major procedure used for synthesizing these kings of complexes consist to prepare a metal-ligand with Schiff base containing two inners of different sizes [6,7].…”

Metal‐organic frameworks (MOFs) are precious resources for future demands in every realm of life. Currently, researchers are striving to create MOF materials with low dielectric constants for the microelectronic sector. In this work, a MOF compound, copper dimandelate (CuDM), is crystallized using the regulated diffusion of cations through viscous reactant media and its suitability for dielectric applications is studied for the first time. The crystallinity of the compound is confirmed and structural characterization is carried out using powder X‐ray diffraction measurements. The various functional groups present in the grown sample are confirmed by Fourier transform infrared and Raman analyses. Thermogravimetric analysis establishes the thermal stability of the material up to a temperature of 220 °C. The predicted chemical formula, (Cu[(C6H5) HOCH COO)]2) is verified by CHNS elemental analysis. The observed dielectric constant varies from 18.55 to 8.15 with applied frequency ranging from 0.01 Hz to 10 MHz, making it suitable for low‐k dielectric applications. The optical band gap and Urbach energy are obtained as 3.65 and 0.6211 eV, respectively, by UV–vis analysis. Solid‐state dielectric parameters, which include valence electron plasma energy, Penn gap, Fermi energy, electrical polarizability, and susceptibility of the material, are calculated using theoretical formulations.
