Abstract
A new two-dimensional antimony sulfide has been synthesized under hydrothermal conditions in the presence of N,N‘-bis(3-aminopropyl)ethylenediamine and characterized by single-crystal X-ray diffraction, thermogravimetry and elemental analysis. The product [C8N4H26]0.5[Sb7S11] (Mr = 1294.07) crystallizes in the triclinic space group, P1, with a = 5.9550(3) A, b = 14.567(1) A, c = 15.093(1) A, α = 68.448(4)°, β = 86.044(6)°, γ = 82.280(6)°, V = 1206 A3, and Z = 2. The structure consists of infinite chains of formula Sb7S112- linked through antimony−antimony bonds (2.921(2) A) into two-dimensional slabs of approximate thickness 2.6 A. These slabs contain pores of dimensions ca. 17.5 × 5.2 A, which are aligned along the [100] direction. N,N‘-Bis(3-aminopropyl)ethylenediamine cations reside between the slabs to which they are hydrogen bonded.
