摘要：

Electrochemical and EPR studies show that the dioxygen-induced decarboxylation and hydroxylation of [Ni-II(GGH-H--2)](-), where GGH is glycyl-glycyl-L-histidine (HL), in aqueous solution occurs via a Ni-III intermediate; the product [Ni-II(Gly-Gly-alpha-hydroxy-D,L-histamine-H-2)].3H(2)O is shown by X-ray crystallography to contain square-planar Ni-II coordinated to the terminal amino group [Ni-N, 1:932(3) Angstrom], two deprotonated amide N's [1.884(3) and 1.831(3) Angstrom] and imidazole delta N [1.908(3) Angstrom].
