| Popis: | Glyphosate (N-(phosphonomethyl)glycine, PMG) is a widely used, commercially available herbicide which is degraded and immobilized upon contact with soil. Since metal ions are believed to play a role in this process, the coordination chemistry of glyphosate is of significant interest. Although several 1:1 metal complexes of glyphosate have been structurally characterized, no 2: 1 complexes have been characterized other than by potentiometric titration. The present work describes the synthesis and crystal structure of Na 3 Co(PMG) 2 .11H 2 O as well as a spectroscopic study of the chromium complex. There are potentially eight geometric isomers for such a ML 2 complex, all of which are formed in solution in the reaction of Na 3 Co(CO 3 ) 3 or CoCl 2 /H 2 O 2 with PMG |
