Abstract

The first tetrafluoroborate compound with XeF2 coordinated to a metal center, Cd(XeF2)2, has been synthesized. It crystallizes in monoclinic space group P21/a with a = 8.785(11) A, b = 9.079(2) A, c = 10.718(6) A, beta = 110.824(6), and Z = 4. Its crystal structure and that of Cd(BF4)2 have been solved. The latter crystallizes in orthorhombic space group Pbca. Both syntheses were performed in aHF as solvent, at room temperature, yielding colorless solids. The Raman spectra of the solids are in harmony with the crystallographic findings. Cd(XeF2)2 has been shown to be in equilibrium with XeF2 and Cd(BF4)2 in aHF.

摘要

首个具有与金属中心配位的XeF₂的四氟硼酸盐化合物Cd(XeF₂)₂已被合成。它以单斜空间群P2₁/a结晶，a = 8.785(11) Å，b = 9.079(2) Å，c = 10.718(6) Å，β = 110.824(6)，且Z = 4。其晶体结构以及Cd(BF₄)₂的晶体结构已被解析。后者以正交空间群Pbca结晶。两种合成均在无水氟化氢作为溶剂的条件下于室温进行，得到无色固体。这些固体的拉曼光谱与晶体学研究结果相符。已表明Cd(XeF₂)₂在无水氟化氢中与XeF₂和Cd(BF₄)₂处于平衡状态。
