An on-column complexation method has been developed for the simultaneous determination of V(IV) and V(V). Vanadium species were chelated with aminopolycarboxylic acids to form anionic complexes which were separated by capillary zone electrophoresis (CZE) with direct UV detection. Ethylenediaminetetraacetic acid

The synthesis of the Fe(III), Co(II), Mn(II), and Ru(III) complexes with two polyamine-polycarboxylate ligands, N-(2-hydroxyethyl)ethylenediamine-N, N', N'-triacetic acid (H3L1) and ethylene bisglycol tetraacetic acid (H4L2) is reported. Potentiometric studies showed that these ligands form stable complexes in aqueous solution and

The [Ru(II)(Hedta)NO(+)] complex is a diamagnetic species crystallizing in a distorted octahedral geometry, with the Ru-N(O) length 1.756(4) A and the RuNO angle 172.3(4) degrees . The complex contains one protonated carboxylate (pK(a)=2.7+/-0.1). The [Ru(II)(Hedta)NO(+)] complex undergoes a nitrosyl-centered one-electron
