The title compound was prepared by the reaction of the elemental components in a tantalum tube. EuAgGe (single crystal. X-ray, Imma, a = 467.0(1), b = 740.0(1), c = 798.1(1) pm, V = 0.2758(1) nm3, Z = 4, wR2 = 0.0371, 474 F2 values and 13 variables) crystallizes with the orthorhombic structure of CeCu2. The europium atoms occupy the cerium positions, while the silver and germanium atoms are randomly distributed on the copper positions. The crystal structure of EuAgGe is discussed together with the structures of EuAg2 and EuAuGe.
