architecture is sustained by intermolecular interactions between pyridyl rings. The yielded product was confirmed by ESI–MS and 1H NMR. In solution, the acetonyl methylene protons have Δδ 0.013 ppm indicating hindered rotation around the methylene carbon–carbonyl carbon bond. In contrast, the solid state chirality of the multidentate ligand was lost in solution.Graphical AbstractThe first non-inclusion
有机汞复合物 [Hg(CH2COCH3)(L)(OCLO3)],其中 L 是拓扑线性的 2,6-双([(2-吡啶基甲基)氧基]甲基)吡啶,已被分离出来并通过 X 射线晶体学表征。新化合物在单斜空间群 P21/c 中结晶,晶胞参数:a = 8.1680(3) Å, b = 16.5794(5) Å, c = 17.3957(5) Å, β = 101.2944(13)°, V = 2310.11(13) Å3, Z = 4. 汞原子与丙酮基亚甲基碳 (2.101(3) Å) 和 L (2.161(2) Å) 的一个末端吡啶基氮有短键,C-Hg-N 角170.67(10)°。一个膨胀的 N2O3 五边形环带包括剩余的四个 L 供体原子和一个高氯酸盐氧,完成了围绕汞的扭曲的五边形双锥配位几何形状。超分子固态结构由吡啶环之间的分子间相互作用维持。所得产物经 ESI-MS 和 1H NMR 证实。在溶液中,丙酮基亚甲基质子的
