Three new compounds (enH)(6+n)Cu(40)Sn(15)S(60) (1), (enH)(3)Cu(7)Sn(4)S(12) (2), and (trenH(3))Cu(7)Sn(4)S(12) (tren = tris(2-aminoethyl)amine) (3) containing Cu(8)S(12) and Cu(7)SnS(12) clusters have been prepared from direct solvothermal reaction of the elements in amine solvents. In 1, the cubic close-packed arrangement of Cu(8)S(12) clusters, interconnected by capping SnS(4) tetrahedra and CuS(3) 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 Cu(7)SnS(12) clusters. The clusters are connected by SnS(4) tetrahedra to form a three-dimensional structure with ReO(3) topology. (119)Sn Mössbauer measurement is consistent with Sn(IV) atoms linking, and Sn(II) atoms within, the mixed-metal Cu(7)SnS(12) clusters.
三种新的化合物(enH)(6+n)Cu(40)Sn(15)S(60)(1)、(enH)(3)Cu(7)Sn(4)S(12)(2)和(trenH(3))Cu(7)Sn(4)S(12)(tren = 三(2-氨基乙基)胺)(3),是通过元素在胺溶剂中的直接溶剂热反应制备的,包含 Cu(8)S(12)和 Cu(7)SnS(12)簇。在 1 中,Cu(8)S(12)簇的立方密堆积排列,通过盖帽 SnS(4)四面体和 CuS(3)三角形相互连接,形成两个相互贯穿的通道网络,其中可能充满无序的溶剂分子。结构 2 和 3 包含有序的质子化胺分子和 Cu(7)SnS(12)簇。簇通过 SnS(4)四面体连接,形成具有 ReO(3)拓扑结构的三维结构。(119)Sn Mössbauer 测量结果与 Sn(IV)原子连接和混合金属 Cu(7)SnS(12)簇内的 Sn(II)原子一致。
