Structural Determination of NaAl2Ga2Intermetallic Compound Having the ThCr2Si2Type Structure.

NaAl2Ga2 intermetallic compound has been synthesized by direct combination of the elements in the atomic ratio Na:Ga:Al = 1:2:2. Guinier–Hagg X-ray and neutron powder diffraction determined a ThCr2Si2 type structure for the new compound with tetragonal unit cell axis a = 4.1817(5) and c = 11.388(2) A.
