The crystal structures of isomorphous SrCl 2 and BaCl 2 hemihydrates were solved by powder diffraction method. Strontium and barium atoms are coordinated either by nine chloride atoms or by seven chloride and two oxygen atoms. Space group: Pmmn(59), lattice parameters: a ‐ 15.976(1), b ‐ 4.260(5), c ‐ 8.090(1) and a ‐ 16.477(5), b ‐ 4.555(1), c ‐ 8.330(3) Å, for strontium and barium compound, respectively. Rietveld refinement results in the discrepancy factors R B ‐ 10.85, R wp ‐ 12.71% and R B ‐ 4.50% for SrCl 2 and BaCl 2 hemihydrate, respectively.
