The new triple-decker compounds 2 (C 32H 33Ni 3PF 6) and 2a (C 42H 53Ni 3PF 6) were synthesised in the reaction of the oxidized 9-nickelafluorenyl sandwich complexes of Nickel (II) 1 (C 27H 28Ni 2PF 6) and 1a (C 32H 38Ni 2PF 6) in acetone. Decomposition of 1 and 1a followed by the stacking of {CpNi} species on compounds 1 and 1a resulted in the formation of the triple-decker complexes. Compound 2 was characterized by X-ray single crystal analysis. It crystallizes from dichloromethane and diethyl ether mixture in the orthorhombic crystal system and in the Pna2 1 space group.
