Bis(triethylammonium) bis(μ-pyrazine-2,3-dithiolato)bis(pyrazine-2,3-dithiolato)diferrate(III) methanol disolvate

Abstract

In the title compound, (C6H16N)2[Fe2(C4H2N2S2)4]·2CH4O, the [FeIII(pdt)2]− anion (pdt is pyrazine-2,3-dithiol­ate) forms a centrosymmetric dimer supported by two FeIII—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 inter­actions, the inter­planar separation between adjacent dimers being 3.51 (2) Å. The methanol solvent mol­ecule 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 triethyl­ammonium cation.
