Aqua[2-(2-pyridyl)-1,8-naphthyridine-κ2 N 1,N 2](2,2′:6′,2′′-terpyridine-κ3 N,N′,N′′)ruthenium(II) bis(hexafluoridophosphate) acetone sesquisolvate
The asymmetric unit of the title compound, [Ru(C13H9N3)(C15H11N3)(H2O)](PF6)2·1.5C3H6O, consists of two crystallographically independent RuII complexes. Each complex is approximately octahedral with the RuII atom bound by an N,N′-coordinated 2-(2-pyridyl)-1,8-naphthyridine (pynp) ligand, a meridional 2,2′:6′,2′′-terpyridine (tpy) ligand and one aqua ligand. The tpy ligand is coordinated in a planar tridentate fashion with the central N atom closest to the RuII atom. The aqua ligand is trans to the pyridine N atom of pynp. The long Ru—O distances [2.150 (5) and 2.138 (5) Å] are typical for aqua ligands in polypyridyl ruthenium complexes. In the crystal, both intramolecular O—H⋯N and intermolecular O—H⋯O hydrogen bonds are observed
