Dichlorido[1-(2-chloroethyl)-3-(pyridin-4-ylmethyl-κN)urea](η6-hexamethylbenzene)ruthenium(II) chloroform monosolvate

Auzias, Mathieu ; Süss-Fink, Georg ; Therrien, Bruno

In: Acta Crystallographica Section E : Structure Reports Online, 2011, vol. E67, no. 11, p. m1613

The RuII atom in the title compound, [RuCl2(C12H18)(C9H12ClN3O)]•CHCl3, exhibits a typical piano-stool coordination, defined by a hexamethylbenzene ligand, two chloride ligands and a pyridylurea ligand coordinated through the pyridine N atom. In the crystal, a dimeric structure is observed due to two strong...
