  consideration of the redox active CuII centres as the initiators of radical species generated from TBHP, which are responsible for the oxidation process of the studied olefins. Electron paramagnetic resonance (EPR) spectra of the reaction solutions, obtained in the presence of the spin trap PBN (N-tert-butyl-α-phenylnitrone), corroborate radical species formation during the oxidation process.

  In the monomeric title compound, [Cu(C4H4O5)(C6H6N2O)(H2O)]center dot 1.5H(2)O, the Cu-II cation is bound in a square-pyramidal coordination to a tridentate oxydiacetate (ODA) ligand, a monodentate pyridine-3-carboxamide (p3ca) ligand and one aqua ligand, where the two organic ligands form the basal plane and the water O atom occupies the unique apical site. The ODA ligand presents a slight out-of-plane puckering in its central ether O atom, while the p3ca ligand is essentially planar. The availability of efficient donors and acceptors for hydrogen bonding results in the formation of strongly linked hydrogen-bonded bilayers parallel to (101), with an interplanar distance of 3.18 (1) angstrom and a stacking separation between the bilayers of 3.10 (1) angstrom, both of them governed by extended pi-pi interactions. The disordered nature of the solvent water molecules around inversion centres is discussed. The monoaqua compound is compared with the octahedral diaqua analogue, [Cu(C4H4O5)(C6H6N2O)(H2O)(2)], reported recently [Perec & Baggio (2009). Acta Cryst. C65, m296-m298].

  In the mononuclear title compound, [Cu(C4H4O5)(C6H6N2O)(H2O)(2)], the Cu-II centre is bound to a chelating oxydiacetate ligand, a monodentate pyridine-3-carboxamide unit and two water molecules, defining an octahedral coordination where the first two ligands form the equatorial plane and the last two occupy the apical sites. The planar oxydiacetate ligand is slightly disordered at its central ether O atom. The availability of efficient donors and acceptors for hydrogen bonding results in a complex interaction scheme where each monomer links to six similar units to define a well connected three-dimensional structure. A comparison is made with related structures in the literature, and the reasons for their differences are discussed.
