High-Pressure Stabilization of Novel Metal-Noble-Gas Complexes and Elusive Metal Fluorides

We propose to explore in situ high-pressure DAC synthesis of novel metal-noble-gas complexes and unprecedented high-oxidation-state metal fluorides by a laser-heating-induced decomposition of extremely potent fluorinators XeF4, XeF6 and KrF+ salts. This research could provide first examples of: Xe coordination to Ag, Ir, Pt cations; coordination of Kr to a metal cation; first crystal structure of organometallic noble-gas complex; and novel high oxidation-state metal fluorides of Ag, Ir, and Au.

本研究拟通过激光加热诱导超强氟化试剂四氟化氙（XeF₄）、六氟化氙（XeF₆）以及氪氟正离子（KrF⁺）盐的分解，开展原位高压金刚石对顶砧（DAC）合成新型金属-稀有气体配合物与前所未有的高氧化态金属氟化物的研究。本研究有望获得如下首例成果：氙（Xe）与银（Ag）、铱（Ir）、铂（Pt）阳离子的配位作用；氪（Kr）与金属阳离子的配位作用；首例有机金属稀有气体配合物的晶体结构；以及银、铱、金的新型高氧化态金属氟化物。
