Abstract

Eu₃(AsS₄)₂ and A_xEu _3-yAs_5-zS₁₀ (A = Li, Na) are the members of a new thioarsenate family. They feature As⁵⁺ and As³⁺ centers, respectively. The rhombohedral Eu₃(AsS₄) ₂ features a new structure type consisting of eight-coordinate Eu²⁺ centers and AsS₄^3- anions, whereas the monoclinic A_xEu_3-yAs_5-zS₁₀ (Li _0.73Eu₃As_4.43S₁₀ and Na _0.66Eu_2.86As_4.54S₁₀) belong to the rathite sulfosalt family and are comprised of apparent [As₁₀S ₂₀]^10- segments linked with Eu²⁺ ions to give a three-dimensional network. They appear to be alkali-metal-stabilized derivatives of the putative parent phase "Eu₃-As ₅S₁₀".
