Shape Configurations:
$$\begin{aligned} \text{XeO}_3 &\implies \text{Pyramidal} \quad (\text{sp}^3\text{ hybridization with 1 lone pair and 3 pi bonds}) \\ \text{XeOF}_4 &\implies \text{Square pyramidal} \quad (\text{sp}^3\text{d}^2\text{ hybridization with 1 lone pair and 1 pi bond}) \end{aligned}$$
Concept: Oxygen-containing xenon compounds obtained typically via partial or complete hydrolysis of xenon fluorides, where the strongly bound oxo group takes part in multiple bonding.
Notation:
- $$\text{XeO}_3$$ = Xenon trioxide;
- $$\text{XeOF}_4$$ = Xenon oxytetrafluoride.
