Abstract

Verschiebung im Kristall: Die NMR‐Spektroskopie eignet sich für die Strukturbestimmung von mikrokristallinen paramagnetischen Festkörpern ohne Isotopenanreicherung. Paramagnetische Effekte, die unter bestimmten Aufnahmebedingungen in ^1^H‐NMR‐Spektren auftreten, werden genutzt, um die Konformation der Moleküle im Gitter und ihre Packung in der Festphase abzuleiten. Die Methode wird anhand der Untersuchung einer Familie von Lanthanoidverbindungen vorgestellt (siehe Bild).magnified image

## Abstract Lanthanide(III) complexes of polyaminocarboxylates are widely used in MRI as contrast agents. The paramagnetic properties of the metal ion contribute to the increase of ^1^H relaxation rates, while the chelate offers a stable binding with the metal. The number of water molecules, coordi
