Abstract
The reaction between Nb2S4aq4+ and K(3)nta (nta is nitrilotriacetate, N(CH2 COO)(3)(3-)), followed by slow oxidation in air, leads to complete desulfur isation of the starting Nb(IV) complex, oxidation of Nb( IV) to Nb( V) and crystallisation of the title complex with hitherto unknown [Nb-2(O)(2)(mu-O H)(2)](4+) core. The crystal structure of the product has been determined. (C) 2000 Elsevier Science S.A. All rights reserved.
