摘要

Two ruthenium carbonyl complexes with the 4′-chloro-2,2′:6′,2′′-terpyridine ligand (tpy-Cl, C15H10ClN3), i.e. [RuCl(tpy-Cl)(CO)2][RuCl3(CO)3] (I) [systematic name: cis-di­carbonyl­chlorido(4′-chloro-2,2′:6′,2′′-terpyridine-κ3N)ruthenium(II) fac-tricarbonyltri­chlorido­ruthenate(II)], and [RuCl2(tpy-Cl)(CO)2] (II) [cis-dicarbonyl-trans-di­chlorido(4′-chloro-2,2′:6′,2′′-terpyridine-κ2N1,N1′)ruthenium(II)], were synthesized and characterized by single-crystal X-ray diffraction. The RuII atoms in both centrosymmetric structures (I) and (II) display similar, slightly distorted octa­hedral coordination spheres. The coordination sphere in the complex cation in compound (I) is defined by three N atoms of the tridentate tpy-Cl ligand, two carbonyl carbon atoms and one chlorido ligand; the charge is balanced by an octa­hedral [Ru(CO)3Cl3]− counter-anion. In the neutral compound (II), the tpy-Cl ligand coordinates to the metal only through two of its N atoms. The coordination sphere of the RuII atom is completed by two carbonyl and two chlorido ligands. In the crystal structures of both (I) and (II), weak C—H⋯Cl inter­actions are observed.
