The tetrahydrofuran-solvated lithium salt of the ato anion [Ni(mes)3]- (mes = mesityl, 2,4,6-Me3C6H2) was obtained as a crystalline solid from the interaction of NiCl2(dme), (dme = 2,2′-dimethoxyethane) and mesityl lithium in Et2O-C4H8O. The blue compound 1 is unstable above ca - 10°C and the X-ray crystal structure was determined at low temperature. The metal centre was found to exhibit an unusual T-shaped coordination geometry, which can be explained in terms of CH3 ... Ni agostic interactions at the fourth site of a formally square-planar NiII centre. Reactions of 1 with donor ligands produced Ni(2,6-Me2C6H3NC)4, Ni(Ph2PCH2CH2PPh2)2 and Ni(mes)2(Me2NCH2CH2NMe2).
