Notizen:
The crystal structure of Zr2Al3C4 was refined by the Rietveld method from conventional X-ray powder diffraction data. The structure was hexagonal (space group P63mc, Z=2) with a=0.334680(6) nm, c=2.22394(3) nm, and V=0.215731(6) nm3, being isomorphous with that of U2Al3C4. The final reliability indices were Rwp=8.57%, Rp=6.06%, and S=1.32. The crystal showed an intergrowth structure with NaCl-type ZrC slabs separated by Al4C3-type Al3C2 layers.
