Abstract A synthesis of the trans-dibromogold(III) t-Bu-Xantphos complex and its self-assembly into infinite 1-dimensional chain in the solid state is reported. The new complex characterized using elemental analyses (C, H, N), ESI-MS, 1H and 13C NMR techniques and X-ray diffraction analysis. Results of DFT calculations followed by the topological analysis of the electron density distribution within the framework of QTAIM method at the ωB97XD/DZP-DKH level of theory reveal that strength of attractive intermolecular non-covalent interactions Br···Br in the crystal is 1.2–1.6 kcal/mol.

有吸引力的卤素……反式二溴金(III)配合物晶体结构中的卤素相互作用

摘要 报道了反式二溴金 (III) t-Bu-Xantphos 复合物的合成及其在固态下自组装成无限一维链的过程。使用元素分析(C、H、N)、ESI-MS、1H 和 13C NMR 技术以及 X 射线衍射分析对新的复合物进行了表征。DFT 计算的结果以及在 QTAIM 方法框架内在 ωB97XD/DZP-DKH 理论水平下对电子密度分布进行拓扑分析的结果表明,晶体中有吸引力的分子间非共价相互作用 Br…Br 的强度为 1.2 –1.6 大卡/摩尔。
