Potentiometric and spectrophotometric studies of Ni(II) coordination to β-alaninehydroxamix acid (β-Alaha) have shown 4N coordination of β-Alaha for 1:2 species and their planar geometry. The geometry of the species formed in the nickel(II)-β-Alaha below ca. pH 7 is octahedral. The differences between the stabilities of zinc(II)-β-Alaha and zinc(ll)-α-alaninehydroxamic acid complexes can be explained by the terdentate coordination of the β-alaninehydroxamic acid.
