摘要: Abstract Formation of a vanadium(V) monoperoxo complex with coordinated N-(carbamoylmethyl)iminodiacetate2− (ada) was observed in the pH range 1.3–8.6. The MI[VO(O2)ada] · xH2O (MI= K+, Cs+; x = 4 for K+ and 1 Cs+) Ba[VO(O2) ada]2 3H2O complexes were isolated from aqueous solution. K[VO(O)2)ada]·H2O obtained by thermal decomposition crystallohydrate. crystal structure K[VO(O2)ada] 4H2O determined X-ray analysis. vanadium atom is seven-coordinated oxo, η2-peroxo tetradentate ada2−-N,O1, O2, O3 ligands. oxygen carbamoyl group apical position trans to VO group.
