原始语种摘要: Abstract(#br)The single crystals of Cs 3 FeCl 5 were synthesized at 973 K using the sealed tube solid-state molten flux method using CsCl as a reactive flux. The polycrystalline sample of Cs 3 FeCl 5 was obtained by the stoichiometric reaction of CsCl and FeCl 2 powders at 823 K by the sealed tube solid-state method. The crystal structure of Cs 3 FeCl 5 was determined by single-crystal X-ray diffraction study at 298 (2) K. This ternary halide crystallizes in the body-centered tetragonal crystal system in I 4/ mcm space group with cell constants of a = b = 9.279 (1) Å and c = 14.824 (3) Å with four formula units per cell. The asymmetric unit of Cs 3 FeCl 5 contains five crystallographically independent atomic sites: Cs1 (site symmetry: m .2 m ), Cs2 (422), Fe1 ( 4 ¯ 2...
