摘要：

The structure of Czochralski-grown lanthanum strontium tetraoxogallate, LaSrGaO4, a K2Ni2F4-type compound, has been redetermined by X-ray diffraction. The improved quality of the crystals resulted in a higher precision in the determination of the geometric parameters than reported previously [Ruter & Muller-Buschbaum (1990). Z. Anorg. Allg. Chem. 584, 119-124]. La and Sr atoms are equally distributed on a nine-coordinate site, and Ga is in a distorted octahedral site stretched along [001]. PIXE analysis gives excellent quantitative results.
