Two new ternary phases, EuCu₈Ga₅ and YbCu₅Ga₇, were prepared by arc-melting. Their crystal structures were investigated on single-crystal X-ray diffraction data. The above mentioned phases crystallize with known structure types, namely, NaZn₁₃ and ThMn₁₂, respectively. Details of the structures (interatomic distances, coordination of the atoms) are briefly discussed.
