Back-bonding in organonickel complexes with terpyridine ligands - A structural approach

A series of organonickel complexes [(R′terpy)Ni(aryl)]X (R′terpy = derivatives of 2,2′;6′,6″-terpyridine; R′ = 4-H, 4-Cl, 4-Tol and 4,4′,4″-tBu3; aryl = 2,6-dimethylphenyl = Xyl or 2,4,6-trimethylphenyl = Mes; X = Br or PF6) have been prepared and characterized. The crystal structures exhibit a number of intermolecular H bond type interactions, but the structure determining force seems to be the packing of the aryl co-ligands. The molecules reveal rather undistorted square planar coordination with a N3C ligand set, the central Ni-N bond being remarkably short, despite the expected strong trans influence of the aryl co-ligands. The longwavelength absorptions were assigned to charge transfer transitions. No emission is observed at ambient temperature in the solid and in solution and at low temperature in glasses.
