Abstract
Two fluorinated metal arsenates, (C4H12N2)1.5[M3F 5(HAsO4)2(AsO4)] (M=Fe, Ga), have been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction, magnetic susceptibility, Mössbauer spectroscopy, and 71Ga NMR spectroscopy. The two compounds are isostructural and crystallize in the monoclinic space group P21/c (No. 14) with a=8.394(1) Å, b=21.992(3) Å, c=10.847(1) Å, β=96.188(2)°, and Z=4 for the Fe compound, and a=8.398(1) Å, b=21.730(3) Å, c=10.679(1) Å, β=95.318(2)°, and Z=4 for the Ga compound. The structure consists of infinite chains of corner-sharing MX6 (X=O, F) octahedra and dimers of edge-sharing MO3F3 octahedra, which are linked into two-dimensional sheets through arsenate tetrahedra with diprotonated piperazinium cations between the sheets. Magnetic susceptibility and Mössbauer spectroscopy confirm the presence of Fe(III). The 71Ga MAS NMR spectrum clearly shows a line shape consisting of three components, corresponding to three crystallographically distinct Ga sites.
