Co-ordination ability of amino acid oximes. Potentiometric, spectroscopic and structural studies of complexes of 2-cyano-2-(hydroxyimino)acetamide

X-Ray crystallographic and solution studies have revealed the first examples of complexes of Cu 2+ and Ni 2+ with an oxime derivative in which completely deprotonated ligand molecules bind in trans position because of the lack of a hydrogen bond between the hydroxyl oxygens which usually stabilises the cis positioning.
