Solution Behaviour

N-Heterocyclic carbene–nickel complexes with five- and four-coordinate geometries [(CNC)NiBr2] and [(CNC)NiBr]X (X = PF6 or BPh4) have been prepared with the pincer ligands 2,6-bis(N-octylbenzimidazolin-2-ylidene)pyridine and 2,6-bis(N-butyl-5,6-dimethoxybenzimidazolin-2-ylidene)pyridine. The addition of the n-octyl substituent significantly extends the solubility of the complexes and has allowed UV-vis solution studies of the complexes in dichloromethane and methanol. The four- and five-coordinate species exist in equilibrium in solution and this equilibrium has been explored by UV-vis studies. The complexes have also been characterized by NMR studies, and single crystal X-ray diffraction studies have been performed on [(CNC)NiBr2] (where CNC = 2,6-bis(N-octylbenzimidazolin-2-ylidene)pyridine) and [(CNC)NiBr]BPh4 (where CNC = 2,6-bis(N-butyl-5,6-dimethoxybenzimidazolin-2-ylidene)pyridine).

Solution Behaviour

The stibines R(Ph)SbCl (1) and R(Mes)2Sb (2) (R = 2-Me2NCH2C6H4) were used to obtain [Me2NHCH2C6H5]+[PdCl3{SbCl(Ph)R}]¬ (3) and [PdCl2{Sb(Mes)2R-N,Sb}] (4). While in 3 the intramolecular N→Sb interaction is preserved, in compound 4 the stibine 2 acts as a (N,Sb)-chelating ligand.
