The crystal structure of [UO2(Hgly)2Cl2] has been solved, revealing the uranium atom to be seven-co-ordinated. The two zwitterionic glycines are coordinated to uranium atom by the carboxylate groups, one in a monodentate and the other in a bidentate mode. Solid state studies and low temperature 1H, 13C, 2D COSY and HMQC solution NMR spectra of the [UO2(mpg)(CH3COO)], show that mpg coordinates uranium atom by the carboxylate group||URI:||http://ktisis.cut.ac.cy/handle/10488/6381||ISSN:||00338230||DOI:||10.1524/ract.2002.90.9-11_2002.549||Rights:||Copyright © Oldenbourg Wissenschaftsverlag GmbH||Type:||Article|
