A new two-dimensional antimony sulfide has been synthesized under hydrothermal conditions in the presence of <i>N</i>,<i>N</i>‘-bis(3-aminopropyl)ethylenediamine and characterized by
single-crystal X-ray diffraction, thermogravimetry and elemental analysis. The product [C<sub>8</sub>N<sub>4</sub>H<sub>26</sub>]<sub>0.5</sub>[Sb<sub>7</sub>S<sub>11</sub>] (<i>M</i><sub>r</sub> = 1294.07) crystallizes in the triclinic space group, <i>P</i>1̄, with <i>a</i> = 5.9550(3)
Å, <i>b</i> = 14.567(1) Å, <i>c</i> = 15.093(1) Å, α = 68.448(4)°, β = 86.044(6)°, γ = 82.280(6)°, <i>V</i> = 1206
Å<sup>3</sup>, and <i>Z</i> = 2. The structure consists of infinite chains of formula Sb<sub>7</sub>S<sub>11</sub><sup>2-</sup> linked through
antimony−antimony bonds (2.921(2) Å) into two-dimensional slabs of approximate thickness
2.6 Å. These slabs contain pores of dimensions ca. 17.5 × 5.2 Å, which are aligned along the
[100] direction. <i>N</i>,<i>N</i>‘-Bis(3-aminopropyl)ethylenediamine cations reside between the slabs
to which they are hydrogen bonded.
