Abstract

The title compounds were prepared from the elemental components by arc-melting and subsequent annealing at 1020 K and 1170 K. Both CePd0.63Ge1.37 and CeAu0.75Ge1.25 crystallize in the AlB2 structure type with a statistical distribution of the transition metal and germanium atomson the boron site. The structure of CeAu0.75Ge1.25 was refined from single crystal X-ray data: P6/mmm, a=433.5(1) pm, c=422.6(1) pm, V=0.0688(1) nm(3), Z=1, wR2=0.0504 for 157 F-2 values and 7 variables. Magnetic susceptibility data for both compounds show a full cerium moment and ferromagnetic ordering at 6.0(5) K for CeAu0.75Ge1.25 and 3.0(5)K for CePd0.63Ge1.37. The crystal structure and properties of CeAu0.75Ge1.25 are compared with those of equiatomic CeAuGe which adopts the NdPtSb structure type, an ordered variant of AlB2. (C) 1997 Elsevier Science S.A.
