Xenon tetrafluoride is a chemical compound with chemical formula XeF 4. It was the first discovered binary compound of a noble gas. [3] ... According to VSEPR theory, ...
Valence shell electron pair repulsion (VSEPR) theory (/ ˈ v ɛ s p ər, v ə ˈ s ɛ p ər / VESP-ər, [1]: 410 və-SEP-ər [2]) is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms. [3]
Numerous compounds adopt this geometry, examples being especially numerous for transition metal complexes. The noble gas compound xenon tetrafluoride adopts this structure as predicted by VSEPR theory. The geometry is prevalent for transition metal complexes with d 8 configuration, which includes Rh(I), Ir(I), Pd(II), Pt(II), and Au(III).
Three oxides of xenon are known: xenon trioxide (XeO 3) and xenon tetroxide (XeO 4), both of which are dangerously explosive and powerful oxidizing agents, and xenon dioxide (XeO 2), which was reported in 2011 with a coordination number of four. [12] XeO 2 forms when xenon tetrafluoride is poured over ice.
Xenon dioxide, or xenon(IV) oxide, is a compound of xenon and oxygen with formula XeO 2 which was synthesized in 2011. It is synthesized at 0 °C by hydrolysis of xenon tetrafluoride in aqueous sulfuric acid : [ 2 ]
A symmetry element can have more than one symmetry operation associated with it. For example, the C 4 axis of the square xenon tetrafluoride (XeF 4) molecule is associated with two Ĉ 4 rotations in opposite directions (90° and 270°), a Ĉ 2 rotation (180°) and Ĉ 1 (0° or 360°).
Structure of xenon oxytetrafluoride, an example of a molecule with the square pyramidal coordination geometry. Square pyramidal geometry describes the shape of certain chemical compounds with the formula ML 5 where L is a ligand. If the ligand atoms were connected, the resulting shape would be that of a pyramid with a square base.
The 3-center 4-electron (3c–4e) bond is a model used to explain bonding in certain hypervalent molecules such as tetratomic and hexatomic interhalogen compounds, sulfur tetrafluoride, the xenon fluorides, and the bifluoride ion.
