Popis:	In a Tutton's-salt like family with Fe atom, three compounds K 2 Fe(SO 4 ) 2 · n H 2 O ( n = 2,4, or 6) are known. The phase transition in K 2 Fe(SO 4 ) 2 ·2H 2 O was already examined by the authors' group. Anomalies of both specific heat and dielectric constant were recently found on K 2 Fe(SO 4 ) 2 ·4H 2 O at 283 K. Structure analyses were performed, therefore, at 300 K (monoclinic, space group C 2/ m ; a = 11.853(1), b = 9.544(1), c = 9.951(1)a, g = 94.81(1)°, V = 1121.7(5)a 3 ; Z = 4) and 123 K ( P 2 1 / a, Z = 4).
