| Abstract | {The rhenium(V) and technetium(V) complexes: [ReO(apa)], [{ReO(epa)}O-2], and [TcOCl(epa)] have been prepared from a potentially pentadentate N3O2 ligand, N,N’-3-azapentane-1,5-diylbis(3-(1-iminoethyl)-6-methyl-2H-pyran-2,4(3H) -dione) (H(3)apa), or a potentially tetradentate N2O2 ligand, N,N’-ethylene-diylbis(3-(1-iminoethyl)-6-methyl-2H-pyran-2,4 (3H)-dione) (H(2)epa). The N2O2 complexes were synthesized in low yields. There was also evidence indicating that H(2)ppa, N,H’-propylene-diylbis(3-(1-iminoethyl)-6-methyl-2H-pyran- 2,4(3H)-dione), hydrolyzed in the course of coordination, forms a rhenium complex of the bidentate monoprotic (O,O) dehydroacetate (dha(-)), [Re(dha)Cl-2(OPPh(3))(PPh(3))]. EtOH. The structure of this complex was determined by X-ray crystallography. Crystals of [Re(dha)Cl-2(OPPh(3))(PPh(3))]. EtOH (C44H37Cl2O5P2Re . C2H6O) are monoclinic |
