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-κ2S, S':κ S)bis-[(cis-1,2-di-phenyl-ethene-1,2-di-thiol-ato-κ2S, S')iron(III)] di-methyl-formamide disolvate

Abstract

The mol-ecular structure of the solvated title salt, (C₂₁H₂₅N₂)₂[Fe₂(C₁₄H₁₀S₂)₄]·2C₃H₇NO 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.

Keywords: crystal structure; imidazolium salt; iron bis­(di­thiol­ene) complexes; reduced iron bis­(di­thiol­ene) complexes.
