Abstract The new ligand bis-bidentate ligand L, containing two pyrazolyl-pyridine chelating units connected to a 1,8-anthracene-diyl core via methylene spacers, reacts with Zn(II), Cd(II) and Cu(II) salts to form trigonal prismatic coordination cages [M6(μ–L)9]12+ in which a metal ion occupies each vertex and a bridging ligand spans each edge; the structure is stabilised by anions which occupy the
摘要 新配体双齿配体 L 含有两个吡唑基-吡啶螯合单元,通过亚甲基间隔基连接到 1,8-蒽-二基核,与 Zn(II)、Cd(II) 和 Cu(II) 盐反应生成形成三角棱柱配位笼[M6(μ-L)9]12+,其中金属离子占据每个顶点,桥接配体跨越每个边缘;该结构通过占据中心腔和三角形面中心间隙的阴离子以及蒽基和吡唑基-吡啶基团之间广泛的配体间芳香堆积来稳定。
