摘要：

CeAuGe was prepared by reaction of the elemental components in an are-melting furnace and subsequent annealing at 800 degrees C. Its hexagonal crystal structure (NdPtSb-type) was refined from single-crystal data of an inversion twin: P6(3)mc, Z=2, a=446.03(7) pm, c=793.60(12) pm, V=0.1367(1) nm(3), wR2=0.060, 213 F-2 values, 11 variables and BASF=0.52(3). In the paramagnetic state, the susceptibility of CeAuGe shows Curie-Weiss behaviour above 50 K with mu(exp)=2.55(5)mu(B) and Theta(p)=-5(1) K. CeAuGe orders ferromagnetically at 10.0(2) K. Its saturation magnetic moment at 5 K is 1.09(2)mu(B)/Ce. Electrical resistivity measurements show metallic behaviour.
