A study of the coordination geometry of the tetrapyridine copper(II) complex in NaY and MCM-41 by two-dimensional electron spin resonance HYSCORE spectroscopy
Article Abstract:
The coordination geometry of the tetrapyridine copper(II) complex in zeolite Cu-NaY and mesoporous siliceous MCM-41 material is investigated by two-dimensional proton and deuterium hyperfine sublevel correlation (HYSCORE) spectroscopy. The different coordination geometries of the tetrapyridine copper(II) complex in both materials result from the interaction of the complex with the inner surface of each molecular sieve. Results indicate a substantial influence of the framework of the Y zeolite on the unpaired electron of the encapsulated complex.

Complexation of copper(II)-chelidamate: A multifrequency-pulsed electron paramagnetic resonance and electron nuclear double resonance analysis
Article Abstract:
Structural information about the copper(II)-chelidamate complex is obtained using multifrequency electron paramagnetic resonance (EPR) and electron nuclear double resonance (ENDOR) techniques. Invoking two-dimensional EPR techniques, additional hyperfine interaction with a 'distant' nitrogen spin, identified, as resulting from the solvent dimethylformamide (DMF), is observed.
