The 4,5,6-triphospha[3]radialene dianion: a phosphorus analogue of the deltate dianion. A NICS(0)πzz examination of their aromaticityThis article is part of the ChemComm 'Aromaticity' web themed issue.Electronic supplementary information (ESI) available: Experimental procedures and spectroscopic data for new compounds, and X-ray crystallographic data of [Li+(dme)3]2·82− and 9.

Reduction of a 4,5,6-triphospha[3]radialene gave the corresponding isolable dianionic species. Despite having two deltate dianion-like π-electrons delocalized over the central framework, its small NICS(0) πzz value (only -2.2 ppm) indicates only limited aromaticity. Reduction of a 4,5,6-triphospha[3...
