The electrical resistivity of high purity CaSi2, CaGe2, SrSi2, SrGe2, BaSi2and BaGe2was measured in the temperature range from 20°C to 800°C by a 4-point technique. CaSi2, CaGe2and SrSi2show metallic, SrGe2, BaSi2and BaGe2semiconducting behaviour. This difference can be explained by the change of the structure of the “anion”-sublattices and the change of the metal-distances in the metal-sublattices.
