Abstract
Complexes of rhodium trifluoroacetate with adenosine (ado), adenosine-5′-momophosphate (AMP), cytidine (cyd), guanosine (guo) and inosine (ino) have been prepared from aqueous or methanolic solutions. They were characterized by elemental analysis, magnetic susceptibility measurements, mass spectra, infrared, visible and nuclear magnetic resonance spectroscopies. In some cases their formation was followed by NMR prior to isolation. They all proved to be diamagnetic and in every compound contain two ligand molecules per rhodium dimer except for the ado complex where the ratio is 1:1. In the solid state it was found that adenosine interacts with the metal via the N(1) and N(7) atoms, its nucleotide through N(7), whereas in the case of cyd, guo and ino their exocyclic oxygen atoms take part in coordination. Solution study seem highly interesting since in some cases more than one species appear.Keywords
