SYNTHESIS AND CONDUCTIVITY OF A NEW SERIES OF ORGANOMETALLIC CHARGE-TRANSFER SALTS

In order to study the relationship between structure and conductivity, ten new organometallic radical ionic salts, [CpFeBz](n)[M(mnt)(2)] an d [CpFeBz](n)[M(dmit)2] (M = Ni, Pd, Pt, Cu, Co; Cp = Cyclopentadienyl ; Bz = Benzene; H(2)mnt = maleonitriledithiole; H(2)dmit = 4,5-dimerca pto-1, 3-dithiole-2-thione; n = 1 or 2), were synthesized according to a new synthetic route. They were characterized using elemental analys is, infrared and H-1-nuclear magnetic resonance spectroscopy. The crys tal structure of [CpFeBz](2)[Ni(mnt)(2)] was determined using X-ray di ffraction. The electrical conductivity of solid state was reported. Co mplexes of [CpFeBz](n)[M(mnt>(2)] showed a low conductivity, while com plexes of [CpFeBz](n)[M(dmit)(2)] exhibited a rather high conductivity in the range of 10(-1)-10(-1) S . cm(-1).
