Compartmental ligands. Part 6. Transition-metal complexes of a non-symmetric, acyclic, Schiff base derived from heptane-2,4,6-trione,1-(o-hydroxyphenyl)butane-1,3-dione, and 1,2-diaminoethane
Abstract
The preparation and metal complexing properties of a non-symmetric, acyclic, Schiff base derived from heptane-2,4,6-trione, 1-(o-hydroxyphenyl)butane-1,3-dione, and 1,2-diaminoethane are described. The ligand has available dissimilar, adjacent, donor sets (N2O2 and O2O2). Both mononuclear positional isomers are found for nickel(II) and copper(II) complexes; oxovanadium(IV), dioxouranium(VI), and cobalt(II) gave only the O2O2 isomer.
