Bis(triethyl-ammonium) bis-(μ-pyrazine-2,3-dithiol-ato)bis-(pyrazine-2,3-dithio-lato)diferrate(III) methanol disolvate.

ABSTRACT: In the title compound, (C(6)H(16)N)(2)[Fe(2)(C(4)H(2)N(2)S(2))(4)]·2CH(4)O, the [Fe(III)(pdt)(2)](-) anion (pdt is pyrazine-2,3-dithiol-ate) forms a centrosymmetric dimer supported by two Fe(III)-S bonds [Fe-S = 2.4787 (4) Å]. In the crystal structure, dimers form a one-dimensional stack along the b axis via π-π stacking inter-actions, the inter-planar separation between adjacent dimers being 3.51 (2) Å. The methanol solvent mol-ecule is involved in two hydrogen bonds in which the hydroxyl group acts as a hydrogen-bond donor to the N atom of a pdt ligand and the O atom acts as an acceptor for the NH group of the triethyl-ammonium cation.
