| Popis: | The two red centrosymmetric Ni(II) tetrameric complexes with defective double-cubane core, [Ni2L2(H2O)]2·0.75 CH3OH (1) and [Ni2L2(CH3CN)]2 (2) (H2L = N-(2-hydroxy-5-methylphenyl)- salicylideneimine), have been isolated and magnetically characterized, emphasizing the effect of the reaction temperature on structural and magnetic properties of isolated complexes. Prevailing antiferromagnetic interactions in the complexes are observed leading to the non- magnetic ground state. Comparation with the known magneto-structural correlations in nickel cubane and dicubane complexes is discussed. |
