Abstract

A three-dimensional iron arsenate [4,4�-bpyH2] 3[Fe9(H2O)6F3(HAsO 4)12(AsO4)2]·2H2O, 1, has been synthesized using 4,4�-bipyridine as the templating agent under hydrothermal conditions. The structure is formed by FeO6, FeO3F3 octahedral units connected with HAsO4 and AsO4 units, forming one- and two-dimensional units in which the one-dimensional units act as a pillar. The presence of face-shared Fe-dimer units in the one-dimensional unit is noteworthy. Detailed magnetic studies indicate two possible magnetic interactions: antiferromagnetic interactions within the layer and a weak ferromagnetic polarization between the layers at very low temperatures through the Fe-dimer units. © 2007 American Chemical Society.
