Abstract
Electron donor acceptor complexes (EDA) of the phenytoin sodium (Pyn) as a rich donor with different pi-acceptors like p-chloranil (p-CHL), 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ), tetracyanoquinodimethane (TCNQ), chloranilic acid (CLA), N-bromosuccinimide (NBS) and picric acid (PA) have been synthesized. Spectroscopic and physical data such as formation constant (K (CT)), molar extinction coefficient (E >(CT)), standard free energy (Delta G (0)), oscillator strength (f), transition dipole moment (mu), resonance energy (R (N)) and ionization potential (I (p)) have been determined. Based on the elemental analysis and photometric titrations the CT-complexes were found to have 1 : 1 stoichiometry.
