Synthesis, Crystal Structures, and Photoluminescence of Lanthanide Coordination Polymers with 4‐Acetamidobenzoate

ABSTRACT.[Sm(H2O)4(NO3)3](4,4'-Hbipy)2(NO3)2 (1) (bipy = bipyridine) has been synthesized via hydrothermal reaction and characterized by X-ray diffraction. The title complex features an isolated structure, based on discrete 4,4'-Hbipy moieties, isolated nitrates and [Sm(H2O)4(NO3)3] species. The samarium ion is in a distorted bicapped square antiprism environment, coordinated by three bidentate nitrates and four coordination water molecules. The 4,4'-Hbipy moieties, isolated nitrates and [Sm(H2O)4(NO3)3] species are held together via hydrogen bonds and … interactions to form a 3-D supramolecular framework. Luminescent investigation reveals a strong emission in blue region. Optical absorption spectrum of 1 reveals the presence of an optical gap of 3.60 eV.

“…In the past few years, 4-acetamidobenzoic acid has attracted increasing attention as a multifunctional ligand (Kashino et al, 1986;Jedrzejas et al, 1995). It shows potential diversified coordination and exhibits various coordination modes, such as monodentate, chelating, and multidentate bridging, etc in those reported complexes (Yin et al, 2011;Wang et al, 2009). Herein we report the synthesis and structure of the title compound.…”

In the title compound, C9H9NO3·H2O, the plane of the acetamide group is oriented at 20.52 (8)° with respect to the benzene ring, whereas the plane of the carboxylic acid group is essentially coplanar with the benzene ring [maximum deviation = 0.033 (1) Å]. In the crystal, classical O—H⋯O and N—H⋯O hydrogen bonds and weak C—H⋯O hydrogen bonds link the organic molecules and water molecules of crystallization into a three-dimensional supramolecular architecture.

“…It is important to establish a solid–liquid equilibrium model. − Most solid–liquid equilibrium models are based on vapor–liquid equilibrium mathematical models, with some modifications. , Considering the properties of the model and the nature of the measurement system, the modified Apelblat equation, the λ h equation, the van’t Hoff equation, and the NRTL equation were selected to fit the experimental data of 278.15 to 318.15 K in three binary solvents.…”

Experimental solubility data of dibenzoylmethane (DBM) in three pure solvents (ethyl acetate, acetonitrile, methylbenzene) and three binary solvents (methanol + water, ethanol + water, and isopropyl alcohol + water) were measured by the gravimetric method from 278.15 to 318.15 K under atmospheric pressure. The experimental results showed that the solubility of DBM increased with the increase of temperature. Moreover, the solubility of DBM was temperature-dependent when the type and composition of solvents remained unchanged. The solubility of DBM decreased with the increase of solvent polarity because the molecular structure of DBM was not conducive to the formation of hydrogen bonds between solute and solvent molecules. The solubilities of DBM were correlated by the modified Apelblat equation, the van’t Hoff equation, the λh equation, and the NRTL equation. The modified Apelblat model produced the best fitting results among these models.
