Do unusual geometries always come from the force exerted by a protein, a solid-state lattice or bulky ligands? In a new iron(II) complex, simple ligands stabilize a square-planar high-spin complex ...

A nanographene compound incorporating five- and seven-membered rings is found to have a highly distorted non-planar structure and serves as a model system for studying the effect of defects in ...

The arrangement of small molecules—known as ligands—around transition metal atoms affects how the metal atoms behave. This is important because transition metals are used as catalysts in the synthesis ...
