addition of simple hydroxamic acids , r1c ( o ) n ( oh ) r2 ( r1 = ch3 , r2 = h ; r1 = c6h5 , r2 = h ; r1 = r2 = ch3 ) , to an aqueous solution of ferrioxamine b at ph = 4.30 , 25.0 degrees c , i = 2.0 , results in the formation of ternary complexes fe ( h2dfb ) a+ and fe ( h3dfb ) a2+ , and tris complexes fea3 , where a- represents the bidendate hydroxamate anion r1c ( o ) n ( o ) r2- .
