New fluorenylnickel complexes [M(THF)(n)](+)[Ni(eta(5)-Flu)(eta(1)-Flu)(2)](-) (M = +48 Li, 1 and M Na, 2) have been obtained in the reaction of nickel bromide with fluorenyllithium and - sodium. The X-ray molecular structures of 1 (monoclinic; P2(1)/c) and 2 (orthorhombic; Fdd2) reveal that in both complexes two fluorenyl ligands are bonded to the nickel atom by eta(1) bond and the third one is bonded to the nickel atom by eta(5) bond. Complexes 1 and 2 are the first structurally characterized nickel complexes bearing fluorenyl ligands.
