dc.description The title compounds were prepared by arc melting of the elements and subsequent annealing. Their structures were refined from single-crystal x-ray diffractometer data. While YAuGe and LaAuGe adopt the structure of NdPtSb, the structures of ScAuGe and LuAuGe are more closely related to that of LiGaGe. The crystal chemistry of these germanides is briefly discussed. The four compounds are weak diamagnets. The ratios of their Pauli susceptibilities and their electronic specific heat coefficients are the same for the Y, La, and Lu compounds. The electrical resistivities of ScAuGe and LuAuGe are metal-like , while YAuGe and especially LaAuGe show much higher resistivities which saturate at high temperatures for LaAuGe at 300 K). The electronic properties of the four compounds are discussed on the basis of TB-LMTO-ASA band-structure calculations. Differences in the phononic specific heat of the compounds result both from the different molar masses and the strong elongation of the lattice parameter c with the R-atom radii.
