Özet
The asymmetric unit of the title compound, (C(14)H(17)N(2)S(2))[Ru(C(10)H(14))Cl(3)], contains a 1,3-bis-(thio-phen-2-ylmeth-yl)-3,4,5,6-tetra-hydro-pyrimidinium cation and a trichlorido(η(6)-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.
