| Abstract: | New derivatives were obtained from Cr(urea)6Cl3· 3H2O in an ethyl acetate medium of chromium(III) with uracil, uridine, 5′UMP, 5′CMP, 5′GMP and 5′IMP. The new derivatives were characterized by elemental analysis, electronic and infrared spectroscopy and thermal analysis. These derivatives proved to be outer sphere complexes, in which the nucleotide, the nucleoside or the base interacts with the starting complex through intramolecular hydrogen bonding.Cr(XMP)(OH)·3H2O (XMP: 5′UMP, 5′CMP, 5′GMP and 5′IMP) complexes were obtained by hydrolysis of the above derivatives of the nucleotides. In these reactions there is a total substitution of the urea molecules. The derivatives obtained by hydrolysis were characterized in solid state by electronic and infrared spectroscopy. These results provide more insight into the biological role of chromium. |
