| Abstract | A series of Ru(II) (1,4-bis(diphenylphosphino)butane) (L)(2) complexes was synthesized from [RuCl2(dppb)](2)(mu-dppb) or RuCl2(dppb)-(PPh3); dppb=Ph2P(CH2)(4)PPh2, L=NH3, pyridine (py), 4-aminopyridine (4-NH(2)py), 4-cyanopyridine (4-CNpy), 4-dimethylaminoppridine (4-Me(2)Npy) 4-methylpyridine (4-Mepy), 4-phenylpyridine (4-Phpy), 4-vinylpyridine (4-Vpy) and N-methylimidazole (MeIm), and L-2=2,2'-bipyridine (bipy), bis(o-pyridyl)amine (bpa), 1,10-phenanthroline (phen), 4,7-diphenylphenanthroline (orbathophenanthroline, bathe) and ethylenediamine ten). The complexes were characterized by elemental analysis, cyclic voltammetry, UV-Vis, NMR and IR spectroscopies. The structures of trans-RuCl2(dppb) (py), (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 P2(1)/c, with Z=4; a=12.946(2), b=14.204(3), c=18.439(4) Angstrom, beta=90.08(2)degrees for trans-3; a=10.694(6), b=18.485(6), c=18.632(7) Angstrom, beta=90.26(3)degrees for cis-4.CH2Cl2; a=17.094(1), b=9.923(2), c=21.905(2) Angstrom, beta=98.883(6)degrees 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 (R-w=0.069, 0.076 and 0.039) for 1957, 4165 and 4824 reflections with I greater than or equal to 3 sigma(I), respectively.
