  五氟化铋与稀有气体氟化物加成反应的拉曼光谱研究

  摘要：

  BiF 5的氟离子受体特性已通过制备几种新的BiF 5二元稀有气体氟化物加合物来评估。该加合物的XeF 4 ·BIF 5，氟化氙4 ·2BiF 5，氟化氙2 ·BIF 5，氟化氙2 ·2BiF 5，2XeF 2 ·BIF 5，KrF受2 ·BIF 5和Cs [毕2 ˚F 11已经通过低温拉曼光谱法制备并表征。尽管可以将化合物描述为一阶近似的离子，但在相应的阳离子和阴离子之间存在相当强的氟化物-桥键相互作用，这表明对键合起了重要的共价作用。本研究补充了稀有气体氟化物与AsF 5和SbF 5之间加合物的先前研究。阳离子-阴离子相互作用的强度可以作为五氟化物酸度的量度。结果表明，BiF 5比SbF 5弱得多的路易斯酸。

  The novel seven-coordinated BiF72- and SbF72- dianions have been prepared and characterized. The Cs2BiF7, Rb2BiF7, K2BiF7 and Na2BiF7 salts were obtained in high yield by heating BiF5 with an excess of the corresponding alkali metal fluorides to about 250 degrees C. Attempts failed to prepare the corresponding BiF83- salts or Li2BiF7 under similar conditions. The [N(CH3)(4)](2)BiF7 Salt was obtained by the combination of excess N(CH3)(4)F with BiF5 in CH3CN solution at -31 degrees C. The (NO2)(2)BiF7 salt was prepared from BiF5 and a large excess of liquid FNO at -78 degrees C and decomposes at room temperature to NOBiF6 and FNO. The corresponding Cs2SbF7, K2SbF7, and [N(CH3)(4)](2)SbF7 salts were also synthesized in a similar fashion, but Na2SbF7 was not formed. The pronounced fluoride ion affinity of SbF6- was further demonstrated by the formation of some Cs2SbF7 when dry CsF and CsSbF6 were ball-milled at room temperature. The BiF72- and SbF72- anions, which are the first examples of binary pnicogen compounds with coordination numbers in excess of six, were characterized by vibrational spectroscopy and ab initio electronic structure calculations. They possess pentagonal bipyramidal, highly fluxional structures of D-5h symmetry, similar to those of IF7 and TeF7-, which are isoelectronic with SbF72-. Although our theoretical calculations indicate that AsF72- is also vibrationally stable, experiments to prepare this dianion were unsuccessful.
