The tripodal ligand N,N′,N″-tri(benzimidazolyl)-methane has been used to synthesize nickel(II) complexes along with an exogeneous ligand, X(X = Cr−,NO3−,ClO4−, HCOO−, OAc− and CNS−). Electronic absorption spectra reveal that the present nickel(II) complexes have six coordinate tetragonal geometries. The value of Racah parameter(B), crystal field splitting parameter (Dq) and term,β0 (which is a measure of covalency) have been calculated.1HNMR spectroscopy reveals a dominantσ-delocalization pattern in these complexes.
