The metal–organic framework (MOF) [Cd(tp)(bpe)]2.2DMF (1) was synthesized solvothermally [DMF; 393 K; 3 days; tpH2 = terephthalic acid and bpe 1,2-di(4-pyridyl)ethylene]. When the analogous reaction conducted hydrothermally, a supramolecular isomer (SI) formed, i.e., [Cd(tp)(bpe)] (2). SI 1 comprises layers, arising from tp κ2O,O′ μ2-κ2O,O′:κ1O coordination, pillared by staves; in 2, both carboxylates of one coordinate mode, other, are μ2-κ2O,O′:κ1O. Solid-state interconversion between 2 not...

Four polymorphs are described for the one-dimensional coordination polymer {Cd[S2P(OMe)2]2(4-pyridine-aldazine)}n (1) which features a trans-N2S4 distorted octahedral geometry. Lattice energy calculations show that room temperature form, 1α, is thermodynamically stable phase, being 1.52 kcal/mol more than 1β form per unit formula. The latter formed at 233 K on cooling 1α based single crystal data. Single crystals of forms and exhibit reversible single-crystal–single-crystal phase change also...

Epilepsy is the third most common known brain disease worldwide. Several antiepileptic drugs (AEDs) are available to improve seizure control. However, associated side effects limit their practical use and highlight ongoing search for safer effective AEDs. Eighteen newly designed fluorine-containing pyrrolylated chalcones were extensively studied in silico, synthesized, structurally analyzed by X-ray diffraction (XRD), biologically toxicologically tested as potential new AEDs zebrafish...
