摘要
摘要 (Bu4N)2[Mo6I8(C≡C-C(O)OCH3)6]与硫酸二甲酯 (CH3)2SO4 反应合成了新的硫酸甲酯配合物 (Bu4N)2[Мо6I8(O3SOCH3)6](I)。根据 XRD 数据，钼原子由单齿甲基硫酸配体配位。在二甲基亚砜溶液中，络合物会发生溶解，同时甲基硫酸配体会被溶剂分子完全取代。簇 I 的粉末样品会发光（磷光），最大发射波长为 620 纳米（77 K）。将温度升高到 300 K 会导致发射最大值移至 650 nm，积分强度降低 1.6 倍。
Methylsulfate Complex (Bu4N)2[Мo6I8(O3SOCH3)6]: Synthesis, Structure, Lability of Ligands, and Phosphorescence
New methylsulfate complex (Bu4N)2[Мо6I8(O3SOCH3)6] (I) is synthesized by the reaction of (Bu4N)2[Mo6I8(C≡C–C(O)OCH3)6] with dimethyl sulfate (CH3)2SO4. According to the XRD data, the molybdenum atoms are coordinated by the monodentate methylsulfate ligands. In a DMSO solution, the complex undergoes solvolysis accompanied by the complete substitution of the methylsulfate ligands by the solvent molecules. A powder sample of cluster I luminesces (phosphorescence) with the emission maximum at a wavelength of 620 nm (77 K). Increasing temperature to 300 K results in the shift of the emission maximum to 650 nm and a decrease in the integral intensity by 1.6 times.
