The new ternary intermetallic compound EuGa_1.682(18)Sn_0.318(18) was synthesized and its crystal structure was determined by X-ray powder diffraction (structure type AlB₂, Pearson symbol hP3, space group P6/mmm, a = 4.3863(2), c = 4.5762(2) Å, Z = 1). The structure is characterized by a statistical distribution of Ga and Sn atoms, which form planar graphite-like 6³ nets stacked in the crystallographic direction [001].
