文摘

Three new compounds (enH)_6+nCu₄₀Sn₁₅S₆₀ (1), (enH)₃Cu₇Sn₄S₁₂ (2), and (trenH₃)Cu₇Sn₄S₁₂ (tren = tris(2-aminoethyl)amine) (3) containing Cu₈S₁₂ and Cu₇SnS₁₂ clusters have been prepared from direct solvothermal reaction of the elements in amine solvents. In 1, the cubic close-packed arrangement of Cu₈S₁₂ clusters, interconnected by capping SnS₄ tetrahedra and CuS₃ triangles, form two interpenetrating channel networks that are presumably filled with disordered solvent molecules. Structures 2 and 3 contain well-ordered, protonated amine molecules and Cu₇SnS₁₂ clusters. The clusters are connected by SnS₄ tetrahedra to form a three-dimensional structure with ReO₃ topology. ¹¹⁹Sn Mssbauer measurement is consistent with Sn^IV atoms linking, and Sn^II atoms within, the mixed-metal Cu₇SnS₁₂ clusters.
