Dichlorido[1-(2-chloro-eth-yl)-3-(pyridin-4-ylmethyl-?N)urea](?-hexa-methyl-benzene)-ruthenium(II) chloro-form monosolvate

The Ru(II) atom in the title compound, [RuCl(2)(C(12)H(18))(C(9)H(12)ClN(3)O)]?CHCl(3), exhibits a typical piano-stool coordination, defined by a hexa-methyl-benzene ligand, two chloride ligands and a pyridyl-urea ligand coordinated through the pyridine N atom. In the crystal, a dimeric structure is observed due to two strong N-H(midline ellipsis)Cl inter-actions between the NH groups of urea and the two chloride ligands of neighbouring mol-ecules. In addition, the C=O group of the urea moiety inter-acts with the solvent mol-ecule through weak C-H(midline ellipsis)O interactions.[on SciFinder (R)]
