Abstract
Acetylsalicylhydroxamic acid (AcSHA) was prepared and characterized. Its pK (a) value was determined as 7.78. Solid metal complexes of AcSHA were also prepared and characterized by elemental analysis, electronic and i.r. spect roscopies, and by magnetic moment measurements. The shift of both hydroxami c and acetyl carbonyl vibrations to lower frequencies clearly indicates tha t AcSHA is bonded through oxygen atoms to the metal ions as a tridentate li gand. On the basis of the experimental data, structures for the complexes a re purposed.
