Abstract
The compound Ce15N7I24 is prepared by reaction of CeI3 and CeN (8:7 mo le) at 1050 K in sealed Ta tubes. It is obtained as red, transparent n eedles which are air and moisture sensitive. The structure of Ce15N7I2 4 contains two crystallographically different types of N atoms. The on e type of N is tetrahedrally coordinated by Ce atoms. The Ce4N tetrahe dra are condensed via opposite edges to form chains. The other type of N has a triangular environment of Ce atoms. Ce15N7I24 is paramagnetic with an effective magnetic moment of 2,55 mu(B).
