Abstract

The title compound, [Fe(C(10)H(20)O(5))(H(2)O)(2)][Fe(2)(C(4)N(2)S(2))(4)]·2C(10)H(20)O(5), consists of an [Fe(II)(15-crown-5)(H(2)O)(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.
