Mixed ligand complexes of ruthenium(II) with α,β-unsaturated β-ketoamines

Ruthenium(II) mixed ligand complexes of the type [(Ru-H(CO)(LL')(PPh3)2)] and [(RuCl(CO)(LL')(PPh3)2](LL'=α, β-unsaturated-β-ketoaminate) have been synthesised by the replacement of H and PPh3 by a bidentate chelating lignad, α,β-unsaturated-β-ketoamine, from [(RuH2(CO)(PPh3)3)] and [(RuHCl)(CO)(PPh3)3)] respectively. All the complexes have been assigned octahedral structures on the basis of elemental analyses. IR, 1H NMR and electronic spectral data. (author). 1 tab., 19 refs
