Draw the resonance structures of $N_2O_5$,state its shape,and indicate the bond angles and bond lengths.

(N/A) $N_2O_5$ (dinitrogen pentoxide) exists as a covalent molecule in the gas phase with the structure $O_2N-O-NO_2$.
Its shape is planar with $C_{2v}$ symmetry.
The central $N-O-N$ bond angle is approximately $112^{\circ}$.
The terminal $N=O$ bonds are shorter (approximately $1.19 \ \mathring{A}$) compared to the $N-O$ bonds connected to the bridging oxygen (approximately $1.35 \ \mathring{A}$).
Resonance structures involve the delocalization of $\pi$-electrons across the $O-N-O$ framework,resulting in partial double bond character for the $N-O$ bonds.
