摘要：
A vanadium(IV) complex VO(sal-glygly) (H2O)(n), (1) (sal-glygly = N-salicylideneglycylglycinate ; n = 1.5-3.0) has been isolated from relatively concentrated solutions containing oxovanadium(IV), glycylglycine and salicylaldehyde, and characterized by elemental analysis, thermal (TG and DSC), magnetic and spectroscopic techniques. From similar but dilute solutions the decavanadate, (NH4)(4)(Na)(2)[V10O28]. 10 H2O (2) was isolated after ageing: its structure has been determined by X-ray diffraction analysis. The NH4+ cations were formed by deamination of the glycylglycine present in solution.
