Low‐Energy Electron‐Induced Dissociation of the Radiosensitizing Agent Sanazole

ChemPlusChem, EarlyView.
Employing mass spectrometry supported by quantum chemical calculations, electron attachment to gas‐phase and microhydrated sanazole, a hypoxic radiosensitizer, is examined. The results suggest that hydration closes and/or slows down the dissociation process and indicates that the initial mechanism of action in a reductive cell environment may be ...

Penta‐ and Hexacoordinated Copper(II) Complexes with Azido and 4‐amino‐3,5‐di‐2‐pyridyl‐4H‐1,2,4‐triazole Ligands with Field‐Induced Slow Magnetic Relaxation

ChemistryOpen, EarlyView.
A field‐induced slow magnetic relaxation was observed in an ionic pentacoordinated Cu(II) complex with 4‐amino‐3,5‐di‐2‐pyridyl‐4H‐1,2,4‐triazole and azido ligands. The analysis of the relaxation behaviour supports the origin of the slow magnetic relaxation in intramolecular low‐energy vibration modes participating in the one‐phonon direct and two ...
