Sodium onoazidoethylenediaminetetraacetatocobaltate(III), (I) has been
synthesized and characterized by elemental and spectral analysis. The
presence of intramolecular hydrogen bonding is suggested based on pK(
a) measurements. The kinetics of the acid hydrolysis of [Co(HEDTA)N-3]
(-) to give [Co(EDTA)](-) is studied and the results are compared with
those for [Co(HEDTA)X](-) ions where X = Cl or Br. The activation par
ameters have also been calculated and the applicability of the compens
ation law has been checked. A mechanistic scheme has been proposed for
the acid-catalysed hydrolysis of the azido complex ion.
