Abstract

Neutron powder diffraction experiments were performed in order to determine the crystal structure of Ce 11B2C2, since the structure of CeB2C2 has been examined only by X-ray techniques and the positions of the B and C atoms in this compound are suspicious. The neutron diffraction pattern reveals that the crystal structure of Ce 11B2C2 has a symmetry with the space group of P4/mbm, where the Ce atoms occupy the 2(a) sites (0,0,0) and the B and C atoms 4(h) sites (x, x + 0.5, 0.5) with positional parameters of xB = 0.361(1) and xC = 0.160(1) at 15.0 K.
