$\text{The structure of }{\mathrm{CrO}}_5\text{ is }$
Oxidation state of $\mathrm{Cr}$ is +6 due to the presence of two peroxide linkages, which can be calculated as. In $\mathrm{CrO}{\left({\mathrm{O}}_2\right)}_2$, let the oxidation state of $\mathrm{Cr}$ be $\mathrm{x}$ $\begin{array}{rl}\mathrm{x}+(-1)4+(-2)& =0\\ \mathrm{x}-6& =0\\ \mathrm{x}& =+6\end{array}$
