-cis-1,2-dicyano-1,2-ethylenedithiolato)bis[(cis-1,2-dicyano-1,2-ethylenedithiolato)ferrate(III)] 1,4,7,10,13-pentaoxacyclopentadecane disolvateAbstract: The title compound, [Fe(C10H20O5)(H2O)2][Fe2(C4N2S2)4]·2C10H20O5, consists of an [FeII(15-crown-5)(H2O)2]2+ cation, sandwiched between and O-H
O hydrogen bonded by two additional 15-crown-5 ether molecules and two independent [FeIII(mnt)2]- anions, where 15-crown-5 ether denotes 1,4,7,10,13-pentaoxacyclopentadecane and mnt denotes cis-1,2-dicyano-1,2-ethylenedithiolate. Each independent [FeIII(mnt)2]- unit forms a centrosymmetric dimer supported by two intermonomer FeIII-S bonds [Fe-S = 2.4715 (9) and 2.4452 (9) Å]. In the crystal structure, the dimers form one-dimensional
-
stacks along the a axis, with an interplanar separation of 3.38 (6) Å.
