| Abstract: | The crystal structure of V2Ga5 has been determined by the method of X-ray diffraction from single crystal oscillation photographs and Debye-Scherrer photographs. The homogeneity range of this phase in the V-Ga system extends approximately from VGa2 to V2Ga5. The crystal belongs to the tetragonal system, the lattice spacings at 18℃ being a = 8.9540? and c = 2.6892?. There are two formula units per unit cell. The space group is D4h5-P4/mbm. The four V atoms are situated at the 4(h) positions, while the ten Ga atoms are situated at the 8(i) and 2(d) positions, with xh= 0.180, xi= 0.070, and yi= 0.210. |
