N2 - Reaction of 1,3-(2-hydroxyphenyl)-1,3-propanedione (BhPPH3), a ligand with three possible sites of coordination acting as a chelating agent, with metal acetates results in the formation of mononuclear species M(BhPPH2)2S,S′ (M=Mn, Fe, Co, Ni, Zn; S,S′=CH3OH, C2H5OH or H2O); M′(BhPPH2)2 (M′=Cu, Pd), and M″(BhPPH2)3S,S′ (M″= Fe, Al). The complexes have been studied by 1H-NMR when possible, and IR spectra. The position of the methine proton (=CH-) at 6.88 ppm in Zn(BhPPH2)2S,S′ indicates that BhPPH3 behaves in mononuclear complexes as a common β-diketone. Most of the complexes lose S,S′ molecules on heating but a crystal structure of Zn(BhPPH2)2 · 2C2H5)OH indicates that the C2H5OH molecules are oxygen bonded to the metal centre. © 1985.
