Abstract

A chiral organic compound that displays magnetic properties has been synthesized for the first time. Two diastereomers of a molecule having an S=3/2 spin state have been characterized by X-ray crystal structure analysis (one of the diastereomers is shown in the space-filling model on the right). Optical resolution of one pair of stereoisomers was possible by chiral stationary phase HPLC.
