1,3-Bis(thio-phen-2-ylmeth-yl)-3,4,5,6-tetrahydropyrimidinium trichlorido(µ6-pcymene)ruthenate(II)

The asymmetric unit of the title compound, (C14H17N2S2)[Ru(C10H14)Cl3], contains a 1,3-bis-(thio-phen-2-ylmeth-yl)-3,4,5,6-tetra-hydro-pyrimidinium cation and a trichlorido(µ6-p-cymene)ruthenate(II) anion. The Ru atom exhibits a distorted octa-hedral coordination with the benzene ring of the p-cymene ligand formally occupying three sites and three chloride atoms occupying the other three sites. The N - C bond lengths of the N - C - N unit of the pyrimidinium cation are shorter than the average single C - N bond length of 1.48 Å, thus showing double-bond character, indicating a partial electron delocalization within the N - C - N fragment. The pyrimidine ring has an envelope conformation. Four inter-molecular C - H?Cl hydrogen bonds generate a three-dimensional hydrogen-bonded framework.
