Single crystals of the ternary compound ErZnGa were synthesized by induction melting. The crystal structure, characterized by an ordered distribution of all atoms, was determined by means of X-ray single-crystal diffraction (diffractometer STOE IPDS IIT, Mo Kα-radiation): structure type LiGaGe (ordered derivative of the CaIn₂ type), Pearson symbol hP6, space group Р6₃mc, a = 4.3928(6), с = 7.0367(14) Å.
