Their structures have been determined and the partial stability of4 in water assessed by a combination of multinuclear NMR spectroscopyand ESI-MS. The heptavanadate unit reported herein could represent an intermediate species in the formation of decavanadate thatis blocked by attachment of tripodal ligands.application/pdfeng© 2021 American Chemical Society.
