Abstract:
The asymmetric unit of the title compound, (C13H15N2S2)[RuCl3(C10H14)], contains a 1,3-(2-thienylmeth-yl)-4,5-dihydro-imidazolium cation and a trichlorido( 6-p-cymene)ruthenate(II) anion. The thio-phene rings of the cation are disordered by an 180° rotation about the thio-phene-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 octa-hedral 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 inter-molecular C - H⋯Cl hydrogen bonds and one C - H⋯π hydrogen bond, forming a three-dimensional hydrogen-bonded network.
