“…The Sn-S bonds range from 2.3901(14) to 2.7024(13) Å for Sn(1) and from 2.3937(14) to 2.7157(13) Å for Sn(2), with corresponding S-Sn-S angles varying from 86.64(4) to 126.39(6)° (Table 1). These values are in good agreement with literature data [38,39]. Interestingly, Sn(3) is surrounded by only three S atoms to form a trigonal pyramidal SnS 3 unit.…”

“…In contrast to other compounds with Sn 3 S 4 units, the divalent Sn atom of the Sn 3 S 4 semi-cube in 1 is trigonally coordinated and has no contact to other sulfur atoms (see An interesting observation is that the anionic chain of (DBNH) 2 Sn 3 S 6 shows similar structural motifs like those in the layered thiostannates R-SnS-1 and R-SnS-3 (R = organic molecule). [38,39] 2-anionic layers are observed containing also Sn 3 S 4 semicubes which are formed by interconnection of SnS 4 tetrahedra. The semi-cubes are joined via two S 2-anions yielding anionic layers with rings consisting of 24 atoms (largest interatomic distances: 10 Å).…”

Solvothermal Syntheses of Two New Thiostannates and an In‐Situ Energy Dispersive X‐ray Scattering Study of Their Formation

Two new thiostannates (DBNH) 2 Sn 3 S 6 (1) and (DBNH) 2 Cu 6 Sn 2 S 8 (2) were synthesized under solvothermal conditions applying Cu, Sn, S and DBN (DBN = 1,5-diazabicyclo[4.3.0]non-7-ene). Compound 1 is a rare example of a mixed-valent thiostannate. The Sn(II) species appears in the rare trigonal-pyramidal environment whereas Sn(IV) is in a tetrahedral coordination. The chain-anion is composed of alternating Sn 3 S 4 semi-cubes and Sn 2 S 2 rings. The structure of 2 consists of undulated anionic layers and amine molecules between the layers. The layers may be viewed as a heteroatom 6 3 graphene layer constructed by condensed CuS 3 triangles and SnS 4 tetrahedra. The two thiostannates coexist which was investigated with in-situ energy dispersive X-ray scattering under real solvothermal conditions. Prior to the formation of 1 and 2 a crystalline intermediate appears which disappears after 60 min.Then reflections of 2 start to grow and reflections of 1 occur some time later. The appearance of a thiostannate(IV) followed by the crystallization of a mixed-valent thiostannate(II,IV) suggests complex redox reactions occurring under the solvothermal conditions. Syntheses without Cu in the reaction slurry lead to the formation of 1 within a very short time. The results of the in-situ studies clearly indicate that the presence of Cu species in solution retards the nucleation and crystallization of 1. The crystalline intermediate was quenched with ex-situ experiments. All syntheses performed with this intermediate do not lead to the crystallization of 1 or 2, i.e., there is no direct relation between these three crystalline compounds. The spectroscopic and thermal properties of 1 and 2 are also discussed.

“…that the molecular cations are present as protonated tren (trenH + ) in agreement with elemental analysis33. In the synthesis of other R-SnS-1 type materials, however, it was reported that the synthesis template may undergo intramolecular structural changes during the solvothermal reaction34. In order to investigate the nature of the templating cation, a solid-state 13 C{ 1 H} CP/MAS NMR spectrum was acquired for a sample of as-synthesized Sn 3 S 7 (trenH) 2 (Fig.…”

The crystalline two-dimensional thiostannate Sn3S7(trenH)2 [tren = tris(2-aminoethyl)amine] consists of negatively charged (Sn3S72−)n polymeric sheets with trenH+ molecular species embedded in-between. The semiconducting compound is a violet light absorber with a band gap of 3.0 eV. In this study the compound was synthesized and functionalized by introducing the cationic dyes Methylene Blue (MB) or Safranin T (ST) into the crystal structure by ion exchange. Dye capacities up to approximately 45 mg/g were obtained, leading to major changes of the light absorption properties of the dye stained material. Light absorption was observed in the entire visible light region from red to violet, the red light absorption becoming more substantial with increasing dye content. The ion exchange reaction was followed in detail by variation of solvent, temperature and dye concentration. Time-resolved studies show that the ion exchange follows pseudo-second order kinetics and a Langmuir adsorption mechanism. The pristine and dye stained compounds were characterized by powder X-ray diffraction and scanning electron microscopy revealing that the honeycomb hexagonal pore structure of the host material was maintained by performing the ion exchange in the polar organic solvent acetonitrile, while reactions in water caused a break-down of the long-range ordered structure.

“…The chalcogenidometalate family encompasses a broad spectrum of compounds with a multitude of applications stemming from their tunable optoelectronic and semiconducting properties; a large subgroup of this family are the chalcogenidotetrelates . A characteristic feature of tin chalcogenide chemistry is the reoccurrence of topologies, such as the [Sn 3 E 4 ] defect—a heterocubane unit (DC, E=S, Se), most often aggregated through further E atoms into frameworks—or the adamantane‐like [Sn 4 E 6 ] tin sesquichalcogenide unit (AD), which is also known for a few tin telluride clusters (E=Te) …”

Reactions of R(1) SnCl3 (R(1) =CMe2 CH2 C(O)Me) with (SiMe3 )2 Se yield a series of organo-functionalized tin selenide clusters, [(SnR(1) )2 SeCl4 ] (1), [(SnR(1) )2 Se2 Cl2 ] (2), [(SnR(1) )3 Se4 Cl] (3), and [(SnR(1) )4 Se6 ] (4), depending on the solvent and ratio of the reactants used. NMR experiments clearly suggest a stepwise formation of 1 through 4 by subsequent condensation steps with the concomitant release of Me3 SiCl. Furthermore, addition of hydrazines to the keto-functionalized clusters leads to the formation of hydrazone derivatives, [(Sn2 (μ-R(3) )(μ-Se)Cl4 ] (5, R(3) =[CMe2 CH2 CMe(NH)]2 ), [(SnR(2) )3 Se4 Cl] (6, R(2) =CMe2 CH2 C(NNH2 )Me), [(SnR(4) )3 Se4 ][SnCl3 ] (7, R(4) =CMe2 CH2 C(NNHPh)Me), [(SnR(2) )4 Se6 ] (8), and [(SnR(4) )4 Se6 ] (9). Upon treatment of 4 with [Cu(PPh3 )3 Cl] and excess (SiMe3 )2 Se, the cluster fragments to form [(R(1) Sn)2 Se2 (CuPPh3 )2 Se2 ] (10), the first discrete Sn/Se/Cu cluster compound reported in the literature. The derivatization reactions indicate fundamental differences between organotin sulfide and organotin selenide chemistry.
