N2 - Single crystals of the ternary Yb0.5Co3Ge3 have been grown out of molten Sn flux and characterized by single crystal and synchrotron powder X-ray diffraction. Yb0.5Co3Ge3 adopts a hybrid YCo6Ge6/CoSn structure, crystallizing in the hexagonal space group P6/mmm with lattice parameters a ≈ 5.1 Å and c ≈ 3.9 Å. Although the compound does not magnetically order down to 2 K, Weiss temperatures of −21 K, −18.7 K, and −21 K for H//a, H//c, and the polycrystalline average, respectively, indicate antiferromagnetic interactions with μeff = 4.23 μB, slightly lower than the full Yb3+ moment of 4.54 μB. Field-dependent magnetization up to 7 T measured at 2, 5, and 10 K show a linear dependence along H//a. Magnetization at 2 K for H//c approaches saturation near 1 μB, lower than the full Yb3+
