Abstract

The reaction of Au with a molten mixture of A₂S/Sb/S (A=Rb, Cs) produced the isostructural quaternary compounds A₂AuSbS₄. The yellow-brown crystals of Rb₂AuSbS₄ (I) and yellow crystals of Cs₂AuSbS₄ (II) are stable in air and water for several days and for over a month for I and II, respectively. The structure of Rb₂AuSbS₄ crystallizes in the space group Pbcm (#57) and at 23°C a=6.804(3) Å, b=20.127(4) Å, c=7.195(4) Å, V=985(1) Å³, Z=8. Final R/R_w =4.5/6.6%. This structure consists of one-dimensional [AuSbS₄]^2n-_n chains separated by A⁺ cations. The chains are comprised of Au⁺ cations linearly coordinated to [SbS₄]^3- tetrahedra. The compounds were characterized with differential thermal analysis (DTA), far-IR, Raman, and solid-state UV/vis diffuse reflectance spectroscopy.
