As many as 13 types of intramolecular hygrogen bonds are determined in 89 conformers of 2?-deoxycytidine nucleoside by means of quantum-chemical analysis (at DFT B3LYP/6-31G(d,p) theory level) of electron density topology with Atoms-in-Molecules (AIM) theory. The total number of H-bonds is 168 and their types are C1?H...O2, C2?H2...O5?, C2?H2...O2, C3?H...O2, C5?H1...O2, C5?H2...O2, C6H...O4?, C6H...O5?, C3?H...HC6, O3?H...O5?, O5?H...O3?, O5?H...O4? and O5?H...O2. Conformational, geometric and electron-topological properties of H-bonds are presented.
Key words: 2?-deoxycytidine, nucleosides, intramolecular hygrogen bonds, electron density topology analysis, quantum-chemical conformational analysis.
