PREPARATION, X-RAY CRYSTAL-STRUCTURES AND ELECTRONIC-PROPERTIES OF N,N'-BIS(2,6-DINITROPHENYL)-1,3-PHENYLENEDIAMINE AND A COMPLEX WITH TETRACYANO-P-QUINODIMETHANE

A novel dimer model for poly(m-aniline), two amino groups of which are effectively shielded by surrounding nitro groups, has been prepared i n good yield and characterised by X-ray crystallographic, electrochemi cal and EPR studies; A 2:1 weak charge transfer complex with tetracyan o-p-quinodimethane has been prepared and showed a moderate electrical conductivity (sigma(rt) = 1.3 x 10(-3) S cm(-1)) in the single crystal line form. The X-ray crystal structure of the complex has also been ex amined in connection with the electrical conductivity.
