Abstract
A PRELIMINARY X-ray investigation of the crystal structure of seleno-urea has been made. The crystals are hexagonal white needles, elongated along the c axis. The values found for the unit cell dimensions are: a = 15.34 ± 0.02 Å c = 12.99 ± 0.02 Å. The number of molecules per unit cell is N = 27; calculated value 27.08, for a density of 2.1 g/c.c.
