characterisation of four new complexes of the [2×2] M4II grid-type (M = Co, Fe, Zn) with oligopyridine-derived ligands. The presence of aminopyrazine and aminopyrimidine moieties at the edge of the ligands potentially enables the formation of infinite hydrogen-bonded multi-grid networks. The ligands were synthesised by subsequent stannylations and Stille-type coupling reactions. The complexes were obtained by
在这里,我们报告了 [2×2] M4II 网格型(M = Co、Fe、Zn)与低聚吡啶衍生配体的四种新配合物的合成和表征。配体边缘氨基吡嗪和氨基嘧啶部分的存在有可能形成无限的氢键多网格网络。配体是通过随后的甲硅烷基化和 Stille 型偶联反应合成的。配合物通过配体与金属盐的自组装获得。对含有氨基嘧啶作为氢键部分的 Co 配合物 7 进行单晶 X 射线结构测定 [P1¯; a = 15.4976(4), b = 18.2114(6), c = 31.9538(10) A, α = 86.9809(13), β = 83.4137(18), γ = 67.2828(16)°]。晶体结构显示出一个方向的氢键,从而形成无限的网格链,而在层的第二个方向,只发现弱的吸引力相互作用。阴离子和溶剂分子位于层之间,从而抑制了它们之间的任何直接相互作用。互补复合物的共结晶应该能够实现以棋盘状方式结合不同金属离子的网格的识别控制交替排列。
