 Abstract: Abstract lt-Ga3Ir is a low-temperature phase in the Ga?Ir system, which is stable below 530?°C. The sample of lt-Ga3Ir was obtained after annealing at 400?°C for 96?hours. The crystal structure of lt-Ga3Ir was solved using 3D-ED electron diffraction data obtained by SA-EDT diffraction tomography, optimized by quantum-mechanical techniques and refined from the X-ray powder diffraction data: structure type Fe3C, space group Pnma, a=6.9073(4) Å, b=7.7275(4) Å and c=4.8536(2) Å, Z=4, Pearson symbol oP16. The striking feature of the chemical bonding is the absence of the two-atomic Ga?Ga bonds. The two-atomic Ga1?Ir and Ga2?Ir, as well as the three atomic Ga1?Ga2?Ir bonds, form the bonding pattern.
