molecules - What's the size of carbon dioxide?

My question is very simple. How big is a carbon dioxide ($\mathrm{CO}_2$) molecule, i.e. the width, length and height of it?

Answer

$CO_2$ molecule

The molecule is linear (all three atoms are in a co-linear line). The C=O bond is 116 pm, so the entire molecule (from centre of O to other O) is 232 pm. The extent in the other directions normal to the axis of symmetry is not well-defined as the electron cloud is diffuse and depends significantly on environment.
