| Abstract: | 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. |
