A large volume of work64 has been published on the determination of stability constants for complexes of hydroxamic acids, e.g. acetohydroxamic acid.65 The stability of 3d transition metal ions (Mn2+ to Zn2+) with salicylhydroxamic and 5-methyl-, 5-chloro-, 5-bromo-, 5-nitro-, 4-chloro-, 4-bromo- and 3-chloro-salicylhydroxamic acids,66 as well as with methyltolylbenzohydroxamic acid,67 has been studied potentiometrically. Stability constants of iron(III) with a number of hydroxamic acids have been determined by redox potential studies.68... 

High resolution structures of urease from B. pasteurii complexed with /3-mercaptoethanol (13) (BME Fig. IB) and acetohydroxamic acid (14) (AHA Fig. 1C) indicate the presence of bridging/chelating coordination to the Ni ions, highlighting the importance of both metal ions in the reactivity of the enzyme. The structures of B. pasteurii urease crystallized in the presence of phosphate...
