Abstract/Summary

Three new isostructural transition-metal thioantimonates [M(dien)2]{Sb18S30[M(dien)]2} (M = Mn (1), Fe (2), Co (3)) have been prepared under solvothermal conditions in the presence of diethylenetriamine (dien). The compounds have been characterised by single-crystal X-ray diffraction, thermogravimetry, elemental analysis, magnetic susceptibility measurements and UV-vis reflectance spectroscopy. The materials crystallise in the space group P-1 and adopt a structure in which complex Sb18S306- chains are cross-linked into layers through transition-metal-dimer bridges, [M2S2], directly bonded to the thioantimonate layers. The layers contain pores, those in successive layers being aligned to generate a channel structure. Additional [M(dien)2]2+ cations are located within these channels in the interlayer space.
