  A series of water-bridged dinickel complexes of the general formula [Ni-2(mu(2)-OH2)(mu(2)-O2CtBu)(2)((O2CBu)-Bu-t)(2)(L)(L')] (L = (HO2CBu)-Bu-t, L' = (HO2CBu)-Bu-t (1), pyridine (2), 3-methylpyridine (4); L = L' = pyridine (3), 3-methylpyridine (5)) has been synthesized and structurally characterized by X-ray crystallography. The magnetic properties have been probed by magnetometry and EPR spectroscopy, and detailed measurements show that the axial zero-field splitting, D, of the nickel(II) ions is on the same order as the isotropic exchange interaction, J, between the nickel sites. The isotropic exchange interaction can be related to the angle between the nickel centers and the bridging water molecule, while the magnitude of D can be related to the coordination sphere at the nickel sites.

  The reaction of NiCl2. 6H(2)O with Me3CCOOH and KOH taken in a molar ratio of 1 : 2 : 2 in water afforded the nonanuclear antiferromagnetic complex [Ni-9(Me3CCOOH)(4)(mu(4)-O)(3)(mu(3)-OH)(3)(OOCCMe3)(12)], which apparently contains Ni-II and Ni-III atoms. The complex was isolated by extraction with CH2Cl2, benzene, or hexane. The reactions of this complex with pyridine bases (pyridine (Py), 3,4-lutidine (Lut), and nicorandil (Nic)) gave the adducts L4Ni2(OOCCMe3)(2)(mu-OOCCMe3)(2)(mu-OH) (L = Py, Lut, or Nic, respectively). According to magnetic measurements, intramolecular ferromagnetic exchange interactions in these adducts are complemented by intermolecular antiferromagnetic interactions. Pyrolysis of the pyridine adduct in air or under an inert atmosphere in xylene yielded the antiferromagnetic complex Py2Ni2(Me3CCOOH)(2)(OOCCMe3)(2)(mu-OOCCMe3)(2), which contains Ni-II atoms. The structures of ail the complexes synthesized were established by X-ray diffraction analysis. The electronic absorption spectra of these compounds are considered.
