Abstract

The new three-dimensional thioantimonate [Fe(C6H14N2)(2)][Sb6S10] was obtained under solvothermal conditions. The compound crystallizes in space group P (1) over bar with a = 6.174(4), b = 9.679(2). c = 12.772(3) angstrom, alpha = 72.08(3), beta = 88.15(3), gamma = 89.51(3)degrees, Z = 2. Trigonal pyramidal [SbS3] units and [SbS4] groups are joined to form a two-dimensional [Sb6S10](2-) layer. The in-situ formed [Fe(C6H14N2)(2)](2+) complexes act like pillars joining the layers into a three-dimensional framework through Fe-S bonds. The Fe-S bond lengths are long which may be caused by a pronounced Jahn-Teller distortion. The optical bandgap of 2.0 eV is in agreement with the brownish color of the compound. The Mossbauer spectrum shows a doublet with an isomer shift typical for Fe2+ in the high spin state. In the Raman spectrum the Sb-S stretching modes of the [SbS3] and [SbS4] groups can be distinguished. Upon heating in nitogen the compound is decomposed in one step yielding Sb2S3 and FeSb2S4.
