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

Abstract

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.
