It must generate the molecule as a mesh. Try reducing the persision: 
less steps = less triangles = smaller file. Can you alter the presision 
of the numbers? You probably don't need 6 to 9 digits presision, 4 may 
be enough, or even 3.
This may result in some facing/bumpiness, but if it may remain to an 
acceptable level.
