SYNTHESIS AND STRUCTURE OF THE MOLECULAR-COMPLEX BETWEEN N-(N',N'-DIMETBYIAMINOPROPYL)PHENOTHIAZINE HYDROCHLORIDE AND 7,7,8,8-TETRACYANO-P-QUINODIMETHANE (DAPP-TCNQ)

Synthesis, spectroscopic, and X-ray structural analysis of the molecul ar complex between the N-(N',N'-dimethylaminopropyl)phenothiazine hydr ochloride, monohydrate, (DAPP) and 7,7,8,8-tetracyano-p-quinodimethane (TCNQ), has been carried out. Crystals of C29H27N6OSCl are monoclinic , P2(1)/c, a = 12.190(2), b = 7.695(2), c = 28.928(3)Angstrom, beta = 91.68(1)degrees. The molecular complex consists of DAPP as donor bindi ng to TCNQ as acceptor by the thiazine central ring and one of the aro matic rings stacking in parallel planes along the c-axis with an inter planar separation of 3.24 Angstrom and 3.16 Angstrom, respectively. Th e electronic and epr spectra of the complex are discussed.
