A multinuclear NMR study of the complexation of W(VI) with meso-2,3-dimercaptos...
Caldeira, M. Madalena; Ramos, M. Luísa; Pereira, Gilberto G.; Gil, Victor M. S.Meso-2,3-dimercaptosuccinic acid (DMSA), which is used as an antidote for heavy metal poisoning and in complexes of 99mTc for diagnostic purposes, forms several complexes with tungsten(VI) in aqueous solutions, as found by 1H, 13C, 17O and 183W NMR spectroscopy. In the pH range ~4-7, there are four complexes in which the acid acts as a bidentate ligand through one carboxyl group and the adjacent sulfhydryl grou...
