摘要：

Proton nmr measurements have been employed to study the formation, stability, and dynamics of the ethylenediaminetetraacetate (EDTA), d7-1,2-propylenediaminetetraacetate (PDTA), trans-(1,2-cyclohexylenedinitrilo)tetraacetate (CyDTA), X-methyliminodiacetate (MIDA), and nitrilotriacetate (XTA) complexes of molybdenum)Y). The EDTA, PDTA, and XTA chelates have been synthesized, isolated, and analyzed for the elements. Nmr spectral evidence indicates the formation of a Mo(V)-MIDA complex in solution; no evidence has been observed for the formation of the CyDTA complex. The nmr spectra establish that these chelates are diamagnetic which implies the existence of dimeric molybdenum units in the chelate structures. Structures have been proposed on the basis of the nmr spectra for the EDTA and PDTA complexes. © 1967, American Chemical Society. All rights reserved.
