XeOF5– and [(XeOF4)3F]– anions - Semantic Scholar
The XeOF5– and [(XeOF4)3F]– anions, which comprise a new class of xenon(VI) oxyfluoro-anion, have been synthesized as their caesium salts and their structures have been characterized for the first time using vibrational spectroscopy and X-ray powder diffraction; the XeOF5– anion displays a stereochemically active lone pair, and the ...

The XeOF 5– and [ (XeOF 4) 3 F] – anions, which comprise a new class of xenon (VI) oxyfluoro-anion, have been synthesized as their caesium salts and their structures have been characterized for the first time using vibrational spectroscopy and X -ray powder diffraction; the XeOF 5– anion displays a stereochemically active lone pair, and the poly...
XeOF5−, ein Anion mit pentagonal‐pyramidaler Struktur
1995年8月4日 · Durch interionische Kräfte nur wenig verzerrt liegt das Anion XeOF −5 (Bild rechts, Bindungslängen in pm) in Kristallen von NO + XeOF −5 vor. Das Xenonatom befindet sich dabei nur wenig oberhalb der durch die Fluoratome aufgespannten Ebene und das doppeltgebundene Sauerstoffatom in der apikalen Position der pentagonalen Pyramide.
Mean amplitudes of vibration of the novel XeF − 5 anion
1992年9月18日 · In conclusion, this study allows a broader insight into the bond and vibrational properties of the interesting XeF5 anion. Its mean amplitudes of vibration confirm the existence of enlarged and somewhat polar bonds.
XeOF , an Anion with Pentagonal-Pyramidal Structure
1995年8月18日 · Only minimally distorted by interionic forces in the crystal, the ion XeOF (picture on the right, bond lengths in pm) can be crystallized as NO + XeOF. The xenon atom is situated only slightly above the plane through the fluorine atoms, and the doubly bonded oxygen atom occupies the apical position of the pentagonal pyramid.
Mean amplitudes of vibration of the pentagonal pyramidal XeOF5…
2000年1月1日 · Mean amplitudes of vibration of the recently reported pentagonal pyramidal XeOF 5− and IOF 52− anions were calculated from vibrational spectroscopic data, in the temperature range between 0 and 1000 K. The results are briefly discussed and some comparisons with related species are made. 1. Introduction.

XeOF5−, an Anion with Pentagonal-Pyramidal Structure
Recent theoretical studies of the molecular and electronic structure of tetra [ (phosphine)gold (I)]- phosphonium cations, [ (H3PAu)4P]+, gave contradictory results favoring either a classical tetrahedral or a unique square-pyramidal structure of the PAu4 unit.
