Abstract
The crystal structure of CsMgCl3 has been determined by Weissenberg technique. The crystals are hexagonal. with two molecules per unit cell of dimensions: a =7.26(2)A. c =6.18(1)A. Cs. Mg and Cl atoms are located at the special positions 2(d), 2(a) and 6 (h) respectively of the space group P63/mmc. After several cycles of least square refinement the reliability factor R converged at 0.068. The structure is isomorphous with that of CsNiCl3.
