Strontium‐Carboxylate‐Based Coordination Polymers: Synthesis, Structure and Dielectric Properties

“…The change in dielectric constant and loss is however insignificant at low temperature (250 and 303 K for 2 and 3 respectively) and at the high‐frequency region. Such decaying behavior has been observed in a similar class of materials reported in the literature; examples include [Sr( BDC )(DMF)], [Sr( TDC )(DMF)] and [Sr(Hbtc)(H 2 O)] . The room temperature dielectric constants were found to be ∼9.7 and ∼12.5 respectively for 2 and 3 (Figure13); the small difference could be attributed to the variance in the polarity of the solvent molecules.…”

Crystal structures, magnetic and electrical properties of two new two-dimensional bis(2-thioxo-1, 3-dithiole-4, 5-dithiolato)nickelate salts

“…In the different dielectric relaxation mechanisms, the process originated from the electronic transitions or the bond vibrations within a molecule appears in the high frequency (f) region with f > 10 12 Hz, and the dielectric relaxation arose from the dipole motion or ionic displace polarization occurs in the frequency regime (f < 10 10 Hz) [31].Thus, the dielectric relaxation appeared in 1 and 2 are attributed to the dipole motion or ionic displace polarization.…”

Thermodynamic models for determination of the solid–liquid equilibrium of 2,5-thiophenedicarboxylic acid in (acetic acid + ethanol) binary solvent mixtures

“…2) [5]. Solution crystallization is commonly used as the final separation and purification step in its production process, where the accurate values of solubility of 2,5-thiophenedicarboxylic acid as a function of the temperature are essential.…”
