Exchange interaction in hybrid spin systems: chloro-meso-tetraphenylporphyrinatochromium(III) derivatives ligated with 3- and 4-(N-oxy-N-tert-butylamino)pyridines
Abstract
The 3d electrons of chromium(III) and the unpaired electron of the nitroxide radical interact ferro- and antiferro-magnetically in chloro-meso-tetraphenylporphyrinatochromium(III) ligated with 3- and 4-(N-oxy-N-tert-butylamino)pyridines to produce quintet and triplet ground states, respectively.
