Use

When editing the contents of a View, drag the Chem 2D NIH icon (below) from the 'External feeds' tab into your view

The Chem 2D NIH (chemnih) plugin returns a Gif image of the 2D structure of any meaningful chemical search term. Valid search terms include a trivial chemical name, systematic (e.g. IUPAC) chemical name, SMILES, InChI or InChIKey. You can set the height and width of the block. You can also select whether the structure is shown in skeletal format (without explicit carbon atom labels or hydrogen atoms) or a fully displayed structure (with all atoms and atom labels).

So, just type in an appropriate term (e.g. ethanol, morphine, buckyball, Cl/C=C\Cl) and you get an (almost) instant image of the 2D structure.

Installation

The latest version of the plugin can be downloaded from Github
