A series of Ru(II) (1,4-bis(diphenylphosphino)butane)(L)2complexes was synthesized from [RuCl2(dppb)]2(μ-dppb) or RuCl2(dppb)-(PPh3); dppb=Ph2P(CH2)4PPh2, L=NH3, pyridine (py), 4-aminopyridine (4-NH2py), 4-cyanopyridine (4-CNpy), 4-dimethylaminopyridine (4-Me2Npy), 4-methylpyridine (4-Mepy), 4-phenylpyridine (4-Phpy), 4-vinylpyridine (4-Vpy) and N-methylimidazole (MeIm), and L2=2,2′-bipyridine (bipy), bis(o-pyridyl)amine (bpa), 1,10-phenanthroline (phen),4,7-diphenylphenanthroline (or bathophenanthroline, batho) and ethylenediamine (en). The complexes were characterized by elemental analysis, cyclic voltammetry, UV-Vis, NMR and IR spectroscopies. The structures of trans-RuCl2(dppb)(py)2 (3), cis-RuCl2(dppb)(bipy) (4) and cis-RuCl2(dppb)(phen) (5) were established by X-ray crystallographic analyses. Crystals of trans-3, cis-4 · CH2Cl2 and cis-5 · solvate are all monoclinic, space group P21/c, with Z=4; a=12.946(2), b=14.204(3), c=18.439(4) A, β=90.08(2)° for trans-3; a=10.694(6), b=18.485(6), c=18.632(7) A, β= 90.26(3)° for cis-4 · CH2Cl2; a=17.094(1), b=9.923(2), c=21.905(2) A, β=98.883(6)° for cis-5 · solvate. The structures were solved by the heavy atom Patterson method and were refined by full-matrix least-squares procedures to R=0.069, 0.071 and 0.036 (Rw=0.069, 0.076 and 0.039) for 1957, 4165 and 4824 reflections with I ≥ 3σ(I), respectively.
