RESUMO
The asymmetric unit of the title compound, [Ru(C(13)H(9)N(3))(C(15)H(11)N(3))(H(2)O)](PF(6))(2)·1.5C(3)H(6)O, consists of two crystallographically independent Ru(II) complexes. Each complex is approximately octa-hedral with the Ru(II) atom bound by an N,N'-coordinated 2-(2-pyrid-yl)-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 Ru(II) atom. The aqua ligand is trans to the pyridine N atom of pynp. The long Ru-O distances [2.150â (5) and 2.138â (5)â Å] are typical for aqua ligands in polypyridyl ruthenium complexes. In the crystal, both intra-molecular O-Hâ¯N and inter-molecular O-Hâ¯O hydrogen bonds are observed.
