Abstract

The reactions of the dilithium derivatives of 9,12-dihalogen-ortho-carboranes 1,2-Li2-C2B10H8-9,12-X2 (X = Cl, Br, I) with mercury chloride HgCl2 afford a number of complexes of the chloride ion with the halogen derivatives of [12]mercuracarborand-4: {[(9,12-X2-C2B10H8-1,2'-Hg)4]Cl}Na·nH2O. The molecular crystal structure of the complex of the [12]mercuracarborand-4 octaiodine derivative with the chloride ion is determined by X-ray diffraction. The substituents at the periphery of the mercury-containing macrocycle are found to exert a substantial effect on the macrocycle geometry leading to the transition from the planar to butterfly conformation, whose geometry is predetermined by a set of intermolecular interactions in the crystal.

卤素取代的 [12]Mercuracarborands-4 的合成。{[(9,12-I2-C2B10H8-1,2'-Hg)4]Cl}Na(H2O)n 的晶体结构
摘要 9,12-二卤代正硼烷 1,2-Li2-C2B10H8-9,12-X2(X = Cl、Br、I)的二锂衍生物与氯化汞 HgCl2 反应,得到了氯离子与[12]巯基硼烷-4 的卤素衍生物的一些络合物:{[(9,12-X2-C2B10H8-1,2'-Hg)4]Cl}Na-nH2O。通过 X 射线衍射测定了[12]巯基硼烷-4 八碘衍生物与氯离子复合物的分子晶体结构。研究发现,含汞大环外围的取代基对大环的几何形状产生了重大影响,导致其从平面构象转变为蝶形构象,而蝶形构象的几何形状是由晶体中的一系列分子间相互作用预先决定的。
