Table 1

General properties of cuprite and tenorite.

Properties	CuO (tenorite)	Cu2O (cuprite)
Crystal structure	The special atomic positions for copper are (1/4,1/4,0); (3/4,3/4,0); (1/4,3/4,1/2); (3/4,1/4,1/2) and for oxygen are (0,y,1/4); (1/2,1/2+y,1/4); (0,y,3/4); (1/2,1/2−y,3/4) with y = 5 0.416(2). Copper atoms are represented by small light spheres and oxygen atoms are represented by large dark sphere	The atomic positions for copper are (0,0,0); (0,1/2, 1/2); (1/2,0,1/2); (1/2,1/2,0) and the tetrahedral sites positions (1/4,1/4,1/4) and (3/4,3/4,3/4) for oxygen.
