Coordination compounds of nickel(II) salts with substituted pyridines. Complexes of 2-, 3-, and 4-methylpyridine

Article abstract of DOI:10.1021/ic50033a014

Complexes of 2-, 3-, and 4-methylpyridine (2-pic, 3-pic, and 4-pic) with a number of Ni(II) salts (chloride, bromide, iodide, nitrate, perchlorate, and tetrafluoroborate) were prepared and investigated. Three series of complexes were obtained, Ni(pic)X₂ (pic = 2-pic, 3-pic; X = Cl, Br); Ni(pic)₂X₂ (pic = 2-pic, 3-pic, 4-pic; X = Cl, Br, I, NO₃); Ni(pic)₄X₂ (pic = 3-pic, 4-pic; X = Cl, Br, I, NO₃, ClO₄, BF₄). The complex Ni(3-pic)₄X₂ (X = ClO₄, BF₄) was obtained in two isomeric forms, identified as [Ni(3-pic)₄X₂] and [Ni(3-pic)₄]X₂, respectively. The complexes of 4-aminopyridine, Ni(4-NH₂py)₄X₂ (X = Cl, Br, I, ClO₄), were also prepared and investigated. The stoichiometry and stereochemistry of the complexes were correlated with the properties of the anion and ligand, in particular with the basicity and steric requirements of the latter.
