The First Example of A Diazaarsolyl Anion: Structure and Coordination Polymerisation of the Aromatic Metallacycle Benzo[1,3,2]Diazaarsolyl Lithium Center Dot 2Thf

The first example of an aromatic diazaarsolyl anion 1 has been synthesised and structurally characterised; the X-ray crystal structure of 1 exhibits planar metallacyclic fragments which link together to generate a coordination polymer via bridging lithium cations.
