文摘

The iron selenidoantimonate(III) [Fe(phen)₃]Sb₆Se₁₀ (1) (phen = 1, 10-phenanthroline) was prepared by reaction of Fe, Sb, Se, phen, and 1, 4-diazabicyclo[2.2.2]octane in MeOH and H₂O mixed solvent under solvothermal conditions. 1 consists of a [Fe(phen)₃]²⁺ cation and a two dimensional [Sb₆Se₁₀]^2– anion. The [Sb₆Se₁₀]^2– anion is constructed by SbSe₃, SbSe₄, and SbSe₆ primary building blocks by corner- and edge-sharing, resulting Sb₄Se₄, Sb₅Se₅, and Sb₆Se₆ heterorings and a semi-cubic Sb₄Se₆ motif, which act as secondary building units. The octahedral SbSe₆ primary unit and semi-cubic Sb₄Se₆ motif make compound 1 quite different from the thioantimonates(III). Compound 1 exhibits steep bandgap (E_g) of 1.56 eV, indicating potential semiconducting property. The thermal stability of 1 was also investigated.
