Temperature and Time-resolved XANES Studies of Novel Valence Tautomeric Cobalt Complex

VT transition from the high-spin CoII to low-spin CoIII state was observed for complex (N-cyclo-hexyl-2-iminopyridine)(3,6-di-tert-butyl-o-benzosemiquinonato)(3,6-di-tert-butyl-catecholato)cobalt in both solid and liquid form. For the first time we demonstrate a low-temperature nanosecond pump-probe...

Zusammenfassung:VT transition from the high-spin CoII to low-spin CoIII state was observed for complex (N-cyclo-hexyl-2-iminopyridine)(3,6-di-tert-butyl-o-benzosemiquinonato)(3,6-di-tert-butyl-catecholato)cobalt in both solid and liquid form. For the first time we demonstrate a low-temperature nanosecond pump-probe XANES experiment revealing the valence tautomeric transition in a solution of Co complex. Reversible transition was induced both under the temperature and laser radiation stimuli.
