The reaction of Li2[C(PPh2NSiMe3) 2] with elemental tellurium in THF was carried out in an attempt to generate the tellurocarbonyl dianion [TeC(PPh2NSiMe3) 2]2- as the dilithium derivative. This thermally unstable tridentate ligand was characterized by 31P and 7Li NMR spectroscopy. Attempted recrystallization gave yellow crystals, which were shown by X-ray crystallography to be a neutral, centrosymmetric complex comprised of two molecules of the novel telluroketone [TeC(PPh2NSiMe 3)2] stabilized by N,Te,N coordination to LiOLi units of the rhombic dodecahedral cluster [Li8(μ5-O) 2(μ5-OH)4(C4H8O) 4].
