We report the structural, magnetic, thermodynamic, and transport properties of EuRh2Ga8, EuRh2In8, and YbCo2Ga8. While the two former compounds show the onset of antiferromagnetic order at 20 and 5 K respectively, the latter remains nonmagnetic down to lowest temperatures. The electrical resistivity of the magnetic Eu-compounds is nearly unaffected by an external magnetic field, but the nonmagnetic YbCo2Ga8 develops a positive magnetoresistance.
