Bis[1,3-bis-(2,4,6-tri-methyl-phen-yl)imidazolium] bis(μ- cis -1,2-di-phenyl-ethene-1,2-di-thiol-ato-κ 2 S , S ':κ S )bis-[( cis -1,2-di-phenyl-ethene-1,2-di-thiol-ato-κ 2 S , S ')iron(III)] di-methyl-formamide disolvate.

The mol-ecular structure of the solvated title salt, (C21 H25 N2 )2 [Fe2 (C14 H10 S2 )4 ]·2C3 H7 NO reveals that the anion is situated on a crystallographic inversion center in the triclinic space group P . The title compound crystallizes utilizing a network of weak π-stacking inter-actions of phenyl rings pertaining to the di-thiol-ene unit. Moreover, the acidic imidazolium H atoms [N-C( H )-N] display non-classical hydrogen-bonding inter-actions of the C-H⋯O type to the oxygen atoms of the N , N -dimethyl formamide solvent, and hydrogen atoms on the backbone of imidazolium rings display weak C-H⋯S inter-actions with the di-thiol-ene sulfur atoms.
