Nickel(I) Complexes with 1,1′-Bis(phosphino)ferrocenes as Ligands. The thermically stable monomeric Nickel(I) complexes [(dtbpf)Ni(acac)] (1) and [(dippf)NiCl] (2) were synthesized and characterized by elemental analyses, EPR spectroscopy, and by X-ray crystal structure analyses of single crystals (dtbpf: 1,1′-bis(di-tertbutylphosphino)ferrocene; dippf: 1,1′-bis(diisopropylphosphino)ferrocene). 1 is formed by reduction of Ni(acac)2 with triethylaluminium in the presence of dtbpf, together with the nickel(0) complex [(dtbpf)Ni(C2H4)]. 1 contains a NiI atom surrounded of two O- and two P donor atoms in a distorted tetrahedral coordination. 2 was obtained by reduction of [(dippf)NiCl2] with NaBH4. In 2 the nickel(I) atom adopts trigonal planar coordination.
