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

چکیده
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 [2.150 (5) and 2.138 (5) Å] are typical for aqua ligands in polypyridyl ruthenium complexes. In the crystal, both intra-molecular O-H⋯N and inter-molecular O-H⋯O hydrogen bonds are observed.

The title compound, {[Cu(C(20)H(14)N(4))(2)][Cu(2)(NCS)(4)]}(n), was obtained by reacting copper acetate hydrate, ammonium thio-cyanate and 4'-(3-pyrid-yl)-2,2':6',2''-terpyridine (3-pytpy) under solvothermal conditions. The polymeric complex is isostructural with the 4'-phenyl-2,2':6',2''-terpyridine (phtpy) analogue. All intramolecular distances and angles are very similar for the two structu...
