[Ni(phen)3]2Sb18S29: A Novel Three-Dimensional Framework Thioantimonate(III) Templated by [Ni(phen)3] Complexes

A Copper(I)-Thioarsenate(III) Inorganic Framework Directed by [Ni(en)3]2

One novel three-dimensional (3-D) copper(I)-thioarsenate(III) [Ni(en)₃]Cu₄As₄S₉ (1, en = ethylenediamine) has been solvothermally prepared with the utilization of the in situ formation of [Ni(en)₃]²⁺ complex as structure-directing agent (SDA). 1 contains cubane-like [Cu₈S₁₂]^16- clusters and rare tetrameric [As₄S₉]^6- units, which are interconnected to generate the first example of a 3-D anionic framework [Cu₄As₄S₉]_n^2n-, topologically identical to pyrite, and having large channels filled by [Ni(en)₃]²⁺ complex cations. 1 is a potential wide-band-gap semiconductor with an energy gap of 1.91 eV that exhibits selectively photocatalytic degradation of methylene blue under visible-light irradiation. The density functional theory calculation, photocurrent response, and magnetic properties of 1 were also investigated.

Two Mercury Antimony Chalcogenides Cs2HgSb4S8 and Cs2Hg2Sb2Se6 with Cesium Cations as Counterions

Two novel layer structure compounds, Cs₂HgSb₄S₈ and Cs₂Hg₂Sb₂Se₆, were synthesized in organic solvent under solvothermal conditions. The Cs₂HgSb₄S₈ is formed of [HgSb₄S₈]^2- ribbons and S atoms by corner sharing. The Cs₂Hg₂Sb₂Se₆ is made up of [SbHg₂Se₆]^5- ribbon and disorder trigonal-pyramidal SbSe₃ by sharing μ₃-Se. These compounds are characterized by single-crystal X-ray diffraction, powder X-ray diffraction, solid-state optical absorption spectra, and so on.

Synthesis, Structure, Band Gap, and Near-Infrared Photosensitivity of a New Chalcogenide Crystal, (NH4)4Ag12Sn7Se22

A new chalcogenide crystal, (NH4)4Ag12Sn7Se22 (FJSM-STS), has been solvothermally synthesized. The crystal structure, which is composed of arrays of [Sn3Se9]n(6n-) chains interconnecting [SnAg6Se10]n(10n-) and [Ag3Se4]n(5n-) layers, is unprecedented among the reported A/Ag/Sn/Q (A = cation; Q = S, Se, and Te) compounds. Optical absorption together with theoretical calculations of the band structure indicate a direct band gap of 1.21 eV for FJSM-STS, which is close to the ideal band gap to maximize the photoconversion efficiency proposed by Shockley and Queisser. The toxic-metal-free crystal of FJSM-STS exhibits obvious photosensitivity in the near-infrared range. The variates of power and temperature on the photosensitivity have been studied.

Surfactant-thermal method to synthesize a novel two-dimensional oxochalcogenide

A new two-dimensional (2D) oxosulfide, (N2H4)2Mn3Sb4S8(μ3-OH)2 (1), has been successfully synthesized under surfactant-thermal conditions with hexadecyltributylphosphonium bromide as the surfactant. Compound 1 has a layered structure and contains a novel [Mn3(μ3-OH)2]n chain along the b-axis. The photocatalytic activity for compound 1 has been demonstrated under visible-light irradiation and continuous H2 evolution was observed. Our results indicate that surfactant-thermal synthesis could be a promising method for growing novel crystalline oxochalcogenides with interesting structures and properties.
