Spectroscopic evidence for the conversion of octahedral nickel(II) into tetrahedral nickel(II)
Journal of the Chemical Society A: Inorganic, Physical, Theoretical, 1970Spectroscopic evidence suggests that the complexes of 8-amino-2-methylquinoline (maq) with nickel(II) of the type, Ni(maq)2X2,nH2O (X = Cl, Br, I, NO3, and CIO4), Ni(maq)2XClO4(X = Cl, I, and NO3), and Ni(maq)X2,nH2O (X = Cl, Br, and I) give rise to tetrahedral species when set aside in methanol.

Nickel(II) Cyanoborates and Cyanoborate-Ligated Nickel(II) Complexes
Inorganic ChemistryNickel(II) cyanoborates Ni[BH2(CN)2]2·H2O (1b·H2O), Ni[BH(CN)3]2·0.5H2O (1c·0.5H2O), and Ni[B(CN)4]2·0.5H2O (1d·0.5H2O) were synthesized, and their reactivity with respect to dppeO2 (=1,2-bis-(diphenylphosphinoethane dioxide)), pyNO (=pyridine-N-oxide), dppe (=1,2-bis-(diphenylphosphinoethane), and DMSO (=dimethyl sulfoxide) was examined.

Transition Metal Chemistry, 1977
Nickel alkoxides react with mono-, di- and tri-ethanolamines in different stoichiometric ratios and novel products have been isolated and characterized by elemental analyses, i.r. and electronic reflectance spectra. Insertions across the Ni-O bond in aminoalkoxides have been studied for the first time.

Biosorption of Nickel (II) and Cadmium (II)
2020Water is a finite limited resource in this planet. This is being threatened both quantitatively and qualitatively by the stress brought about by increasing population and industrial activities. Heavy metals are natural elements extracted from earth and exploited in industrial applications which, generally, have high densities.

Nickel(II)‐imprinted monolithic columns for selective nickel recognition
Journal of Applied Polymer Science, 2010AbstractNi2+‐imprinted monolithic column was prepared for the removal of nickel ions from aqueous solutions. N‐Methacryloyl‐L‐histidine was used as a complexing monomer for Ni2+ ions in the preparation of the Ni2+‐imprinted monolithic column. The Ni2+‐imprinted poly(hydroxyethyl methacrylate‐N‐methacryloyl‐L‐histidine) (PHEMAH) monolithic column was ...
