摘要：

The structure of CePd2Al3 has been studied by single-crystal X-ray diffractometry and was refined to the R(R(w)) values 0.035(0.028). The CePd2Al3 compound crystallizes in hexagonal symmetry belonging to the space group P6/mmm; the lattice constants are: a = 5.4764(2) angstrom, c = 4.2187(2) angstrom. It is corroborated that the structure is a CaCu5-type derivative, with Pd and Al atoms, respectively, replacing the Cu atoms on two crystallographically distinct structure sites. An occupational refinement of the atom sites indicated the presence of an appreciable proportion of vacant sites (ca. 4%) at the Pd position.
