Abstract

The two new thiostannate compounds (trenH)2Sn3S7 (1) and {[Mn(tren)]2Sn2S6} (2) (tren=tris2-aminoethylamine) were obtained under solvothermal conditions. Compound 1 crystallizes in the hexagonal space group P63/mmc with a=13.2642(19), c=19.078(3) Å, V =2906.9(7) Å3. The layered [Sn3S7]2− anion is constructed by Sn3S4 semi-cubes sharing common edges. The layers are characterized by large hexagonal pores with dimensions of about 11×11 Å2. Compound 2 crystallizes in the triclinic space group P¯1 with lattice parameters a=7.6485(7), b=8.1062(7), c=12.1805(11) Å, α=97.367(11), β =103.995(11), γ= 108.762(10)◦, V =676.17(10) Å3. The [Sn2S6]4− anion is composed of two edge-sharing SnS4 tetrahedra and joins two Mn2+-centered complexes by Mn–S bond formation. The Mn2+ cation is in a trigonal-bipyramidal environment of four N atoms of the tren ligand and one S atom of the thiostannate anion. Both compounds are semiconductors with a band gap of 2.96eV for 1 and of 2.75eV for 2.
