A self assembled molecule of 18 iron atoms (blue) plus carbons (brown) and oxygens (white), created in the laboratory and here modeled on a computer, reveals itself as beautiful architecture.
The molecule, formed by the reaction of iron salts with specialized bridging groups comprising carboxylic acid units, represents an interesting form of matter between simpler iron compounds and bulk materials. It has turned out to have interesting magnetic properties.
