Journal Article
Jornet-Mollá, V., Giménez-Saiz, C., Yufit, D. S., Howard, J. A., & Romero, F. M. (2021). A reversible hydrogen‐bond isomerization triggered by an abrupt spin crossover near room temperature. Chemistry - A European Journal, 27(2), 740-750. https://doi.org/10.1002/chem.202003654

The spin crossover salt [Fe(bpp) 2 ](isonicNO) 2 ·2.4H 2 O ( 1 ·2.4H 2 O) (bpp = 2,6‐bis(pyrazol‐3‐yl)pyridine; isonicNO = isonicotinate N‐oxide anion) exhibits a very abrupt spin crossover at T 1 /2 = 274.4 K. This triggers a supramolecular linkage... Read More about A reversible hydrogen‐bond isomerization triggered by an abrupt spin crossover near room temperature.

Isoniazid is a key antitubercular agent which exhibits poor chemical stability in the solid state. Cocrystallization with hydroxyl derivatives of cinnamic acid, which themselves possesses antitubercular and antioxidant activity, may produce solid for...
