Diaqua-(1,4,7,10,13-penta-oxacyclo-penta-deca-ne)iron(II) bis-(μ-cis-1,2-dicyano-1,2-ethyl-enedithiol-ato)bis-[(cis-1,2-dicyano-1, 2-ethyl-enedithiol-ato)ferrate(III)] 1,4,7,10,13-penta-oxacyclo-penta-decane disolvate

The title compound, [Fe(C10H20O5)(H2O)2][Fe2(C4N2S2)4]·2C10H20O5, consists of an [Fe^II(15-crown-5)(H2O)2]²⁺ cation, sandwiched between and O - H⋯O hydrogen bonded by two additional 15-crown-5 ether mol-ecules and two independent [Fe^III(mnt)2] ^- anions, where 15-crown-5 ether denotes 1,4,7,10,13-penta-oxacyclo- penta-decane and mnt denotes cis-1,2-dicyano-1,2-ethyl-enedithiol-ate. Each independent [Fe^III(mnt)2]^- unit forms a centrosymmetric dimer supported by two inter-monomer Fe^III - S bonds [Fe - S = 2.4715 (9) and 2.4452 (9) Å]. In the crystal structure, the dimers form one-dimensional π-π stacks along the a axis, with an inter-planar separation of 3.38 (6) Å.
