- W2022672958 abstract "Abstract Blue paramagnetic (μ = ∼3·2 B.M.) complexes having formulas [Ni(X-py)4(ClO4)2], where X is H, 3-CH3, 3-Br, 4-C2H5, 3,5-(CH3)2, and 4-i-C3H7, are reported. Also, yellow diamagnetic [Ni(X-py)4](ClO4)2 complexes, where X is 4-CH3 and 4-NH2, and the slightly paramagnetic yellow [Ni(3-pic)4](ClO4)2 complex are reported. Characterization of the complexes include studies of the infrared, near-infrared, and visible spectra of the solid complexes and their solutions in the component pyridine base and in acetone. Near-infra-red and visible absorption bands are assigned in agreement with either regular or distorted octahedral stereochemistries for the blue complexes and solutions and in agreement with square-planar stereochemistry for the yellow complexes. The co-ordination of the perchlorate ion to the nickel ion in the blue complexes is confirmed from the splitting of the degenerate modes and the activation of the symmetric modes of the perchlorate ion in the infra-red spectrum. The ability of two of the complexes to form clathrates with aromatic guests is observed. Inductive, steric, and resonance effects of the substituents are considered as possible explanations of the observed substituent effects. The influence of the resonance effect on the possibility of synergic bonding between the nickel and the pyridine base is considered to be the most important factor in determining the stereochemistries of the complexes. The value of Δ for the 3- and 4-substituted pyridines is judged relatively insensitive to the substituent group." @default.
