Synthesis, spectral and RAHB studies on some arylhydrazones of β-diketones: crystal and molecular structures of 2-(2-(3-pyridyl)hydrazono)-5,5-dimethylcyclohexane-1,3-dione and 2-(2-(2-methoxyphenyl)hydrazono)-5,5-dimethylcyclohexane-1,3-dione

Single crystal electron paramagnetic resonance spectra of CuII ions in Cu(tyrosine)2

“…3. One of the paths connects CuA with CuB labeled as P AB (or CuC with CuD) and spatially separated by 13.452 Å belong to neighboring chains, which contains one resonance assisted hydrogen bond (RAHB [36][37][38]) linking one oxygen atom from a phenyl group (O3A) with another oxygen from a carboxylate group (O4B), d[O3A•••O4B] =2.621 Å (Fig. 3).…”

“…Within the strong hydrogen bond category the resonance assited hydrogen bond (RAHB) can be mentioned. The RAHB are produced by the interactions between molecules with multiple π conjugated bonds [36][37][38]. On the other hand, metal ions with unpaired spins are coupled by dipolar and exchange interactions [39].…”

Interplay of thermochemistry and Structural Chemistry, the Journal (volume 22, 2011, issues 1–3) and the discipline

“…The experimental paper by Sethukumar et al [22] is a report on the synthesis of a series of arylhydrazone derivatives of acetylacetone and dimedone and their characterization by electronic, IR, and NMR spectroscopy. To 2-(2-(3-pyridyl)hydrazono)-5,5-dimethylcyclohexane-1,3-dione and 2-(2-(2-methoxyphenyl)hydrazono)-5,5-dimethylcyclohexane-1,3-dione X-ray single crystal structures were determined.…”

Synthesis, Characterization, DFT, and In Silico Investigation of Two Newly Synthesized β-Diketone Derivatives as Potent COX-2 Inhibitors

“…Currently, the realm of β-diketones stands as a captivating focus of exploration owing to its noteworthy biological impact [1][2][3]. Analytical chemistry frequently employs β-diketones as a group of spectrophotometric reagents due to their remarkable ability to form complexes [4][5][6][7][8][9].…”
