✦ Synopsis

In the title compound, C 19 H 12 FNO, the dihedral angle between the mean planes of the 9H-xanthene moiety and the 3-¯uorophenyl group is 82.5 ( 1) . An intramolecular CÐ HÁ Á Á% interaction stabilizes the molecular conformation.

## Abstract A new monoxanthen‒9‒yl derivative of urea has been synthesized and the structure of this product (__N__‒9 __H__‒xanthen‒9‒ylurea) and that of the previously known __N__,__N__′‒di‒9 __H__‒xanthen‒9‒ylurea have been proved by ^15^N NMR and other spectroscopic techniques. A series of ^13^C
