Abstract

The reaction of N-methylpyridinium iodide, Mepy(+)I(-), and tetracyanoethylene (TCNE) forms [Mepy](2)[TCNE](2), which possesses [TCNE](2)(2-) with an intradimer C-C bond distance of 2.806(1) angstrom at 50 K from X-ray diffraction, and 2.801(4) angstrom at 50 K from neutron diffraction. In the IR it exhibits v(C N) absorptions at 2191, 2174, 2169, 2163 and a v(CC) absorption at 1366 cm(-1), with UV/Vis absorption bands at 26,880 and 18,520 cm(-1). Analysis of the cation-hydrogen to [TCNE](2)(2-) interactions do not provide evidence that the cation stabilizes formation of the [TCNE](2)(2-) dimer, which is stabilized by the intradimer 2e(-)-4 center C-C bonding interaction.
