## Abstract A new monoxanthenβ€’9β€’yl derivative of urea has been synthesized and the structure of this product (__N__β€’9 __H__β€’xanthenβ€’9β€’ylurea) and that of the previously known __N__,__N__β€²β€’diβ€’9 __H__β€’xanthenβ€’9β€’ylurea have been proved by ^15^N NMR and other spectroscopic techniques. A series of ^13^C
