One dimensional channels are formed in the three-dimensional open-framework iron selenite [C4N2H12]0.5[Fe2F3(SeO3)2] (I), which was synthesized hydrothermally from FeCl3⋅6 H2O, HF, and SeO2 in the presence of the organic amine piperazine. The same inorganic framework was also obtained with the amines diethylenetetramine, 1,3-diaminopropane, and ethylenediamine. Compound I displays unusual magnetic frustration behavior that is attributed to the tetrahedral geometry.
