Abstract

{Several triply-bridged diruthenium(II)(1,4-bis(diphenylphosphino)butane) complexes were synthesised and characterised by elemental analysis, UV-Vis, NMR and IR spectroscopies, The solid-state structures of [(dppb)ClRu(mu-D2O)(mu-Cl)(2)RuCl(dppb)] (1), [(eta(2)-H-2) (dppb)Ru(mu-Cl)(3)RuCl(dppb)] (2) and [TMP][(dppb)ClRu(mu-Cl)(3)RuCl(dppb)] (3) were established by X-ray crystallographic analyses (TMP=1,1,3-trimethyl-2,3-dihydroperimidinium; dppb = Ph2P(CH2)(4)PPh2). Crystals of 1.1.5C(6)D(6), 2.1.5C(7)D(8) and 3.2Me(2)CO.2H(2)O are all monoclinic, space groups P2(1)/c, P2(1)/n and C2/c, respectively, with Z=4: a=16.8681(6)
