چکیده :
Quantum mechanical ab initio calculations at the HF/6-31G** level and the DFT method at the B3LYP/6-31G** level have been used to predict the binding energies and geometries of the dacarbazine-BX3 (X=F, Cl) system. Four different conformers corresponding to the minimum points on the molecular energy hyper surface were found for each of the dacarbazine-BF3 and dacarbazine-BCl3 systems. In conformers of (a) and (e), the oxygen atom of cytosine donated its lone-pair electron to the empty p orbital of the boron atom and it exhibited the most structural stability.
