Abstract: The asymmetric unit of the title compound, (C₁₃H₁₅N₂S₂)[RuCl₃(C₁₀H₁₄)], contains a 1,3-(2-thienylmethyl)-4,5-dihydroimidazolium cation and a trichlorido(⁶-p-cymene)ruthenate(II) anion. The thiophene rings of the cation are disordered by an 180° rotation about the thiophene-CH₂ bonds with occupancies of 0.847 (5)/0.153 (5) and 0.700 (5)/0.300 (5), respectively. The Ru atom exhibits a distorted octahedral coordination with the benzene ring of the p-cymene ligand formally occupying three sites and three Cl atoms occupying the other three sites. The short C-N bond lengths in the imidazoline ring indicate partial electron delocalization within the N-C-N fragment. Cation and anions are connected through five intermolecular C-HCl hydrogen bonds and one C-H hydrogen bond, forming a three-dimensional hydrogen-bonded network.
