The pH-dependent water-exchange rates of [(CO)2(NO)Re(H2Ocis)2(H2Otrans)]2+ (1) in aq. media were investigated by means of 17O NMR spectroscopy at 298 K. Because of the low pKa value found for 1 (pKa = 1.4 ± 0.3), the water-exchange rate const. kobsH2Otran ...
The molecular forms of LiF, LiFHF and Na2SiF6 have been stabilized using trinuclear metallamacrocyclic complexes of (cymene)Ru-II, (Cp*)Rh-III and (Cp*)Ir-III as specific receptors. The host-guest complexes were characterized by NMR spectroscopy and single ...
