N2 - The new three-dimensional thioantimonate [Fe(C6H14N2)2][Sb6S10] was obtained under solvothermal conditions. The compound crystallizes in space group P$\bar{1}$ with a = 6.174(4), b = 9.679(2), c = 12.772(3) Å, α = 72.08(3), β = 88.15(3), γ = 89.51(3)°, 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 Mössbauer 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.
