چکیده
The title com pound was prepared by the reaction of the elem ental com ponents in a tan ta lum tube. EuA gG e (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 orthorhom bic structure of C eC u2. The europium atom s occupy the cerium positions, while the silver and germ anium atom s are random ly distributed on the copper positions. The crystal structure of EuA gG e is discussed together with the structures of E uA g2 and EuAuGe.

متن کاملThe effect of preparation method and presence of impurity on structural properties and morphology of iron oxide
In this paper, the effect of the structural properties and morphology of iron oxide product, have been studied in co-precipitation and hydrothermal methods. Also, the effect of adding CCl4 impurities and final annealing of the materials is taken into account. The more homogeneous particle size in hydrothermal method has been explained by the effect of adding CCl4 as impurities to prevent the co...
