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.
