摘　　要：本文用x-射线粉末法对CaGa_4的晶体结构进行了研究。结果表明:该晶体属单斜晶系;空间群为C(?)_h—C_(2/m);晶胞参数a=618.4pm,b=613.2pm,c=612.0pm,β=118.90~2;z=2。The preparation and crystal structure determination of CaGa4 by x-ray powder diffrcation have been reported.It shows that the cell parameters for the species of CaGa4 are : a = 618.4pm, b=613.2pm, c = 612.0pm, β=118.90°. Monoclinic and space group C2/m, Z = 2,
