One-dimensional metallic conductance was observed along the <I>c</I> axis of a single crystal of benzo[<I>b</I>]phenothiazine–iodine complex, (B[<I>b</I>]PT)<SUB>2</SUB>(I<SUB>3</SUB><SUP>−</SUP>)(I)<SUB>2</SUB>, the crystal structure of which was preliminarily determined by X-ray analysis. Its metal-insulator transition was observed around 235 K, and the sign of the carriers seemed to be positive above 250 K. From the reflection spectra, with polarized light parallel to the c axis, a plasma-edge-like dispersion was observed in near IR region. Several parameters were evaluated by assuming a tight binding band model. The EPR spectra of this complex consist of only one broad signal (peak-to-peak width at room temperature 250×10<SUP>−4</SUP> T) in the temperature range from 4 K to 296 K (<I>g</I>=1.998±0.002).
