The T1 and T2 crystalline varieties of the ternary carbide Al2MgC2 were synthesized by reacting graphite particles with Mg-Al melts at 930–1020 K. Below 1000 K, the T1 variety was predominant but little amounts of T2 were also present. At 1000 K and above, only the T2 variety was obtained. Assuming a hexagonal close packing of the metal atoms, the crystal structure of T2-Al2MgC2 was determined by Rietveld refinemenent from X-ray powder diffraction data.
