The homochiral inorganic-organic hybrid compound (H(3)NHPA)(SnCl(3))(2)(H(2)O)(3) [1, (S)-4-(4'-aminophenyl)-2-aminobutanoic acid diammonium trichloride stannite triaqua] has a TGS (triglycine sulfate)-like structure. Preliminary investigation suggests a possible ferroelectric behavior with a saturation spontaneous polarization (P(s)) of ca. 3.5 microC.cm(-)(2), which is slightly greater than that of TGS (P(s) = 3.0 microC.cm(-)(2)).

The reaction of H‐Norf with (NH4)2Fe(SO4)2·6H2O and Fe(OH)3 (or Fe2O3) affords Fe(H‐Norf)2(SO4)·2H2O (1) and Fe(Norf)2·4H2O (2), respectively, both of which have 2D polymeric structures. Their interesting magnetic properties are also reported.
