An Unusual Ditelluride: Synthesis and Molecular and Electronic Structures of the Dimer of the Tellurium‐Centered Radical [TePiPr2NiPr2PTe].

Facile formation of the ditelluride [(TePiPr2NiPr2PTe-)2], which exists as a centrosymmetric dimer (see picture: Te green, P purple, N blue, C gray) with a weak TeTe bond, embodies a new feature of the chemistry of dichalcogenoimidodiphosphinate ligands. The monotelluride HPiPr2NiPr2PTe analogue is obtained as the PH tautomer.
