Abstract

Single crystals of the title compound are monoclinic, space group P2~1~/n with two formula units per cell of the following dimensions: a = 18.209, b = 19.076, c = 4.075 Å, β = 92.43°. The crystals show metallic conductivity along the needle axis from room temperature down to ca. 180 K, the maximum conductivity at room temperature being 455 (Ω cm)^−1^.

The unoxidized (iodine free) parent compound crystallizes n the monoclinic space group P2~1~/c with 2 molecules per cell of dimensions: a = 4.988, b = 20.192, c = 11.871 Å, β = 94.41°.
