Abstract

original image

Die Diffusion von NO-Gas in Kristalle aus [(TPP)Fe(H2O)]SO3CF3 (1) führt zur Nitrosylierung der Hälfte aller Moleküle unter Bildung von [(TPP)Fe(NO)(H2O)]SO3CF3 (2). Diese Festphasenreaktion geht mit einer deutlichen Verschiebung der Porphyrine einher, um Platz für die NO-Liganden zu schaffen. Weil beide Molekülarten in demselben Kristall vorliegen, können ihre geometrischen Parameter direkt verglichen werden. TPP=Tetraphenylporphyrin; C schwarz, N blau, O rot.
