| Abstract: | Two tetranuclear clusters of formula M4L4(HOMe)4] {H2L = (E)‐1‐(2‐(hydroxymethyl)phenylimino)methyl]naphthalen‐2‐ol} M = Co ( 1 ), Ni ( 2 )] were hydrothermally synthesized by reaction of M(OAc)2 · 4H2O with H2L and NaOH in MeOH. X‐ray crystal structure analysis revealed that complexes 1 and 2 are isostructural. In the core of the structures, four MII ions and four oxygen atoms occupied alternate vertices of M4O4] cubane. The magnetic property measurements of 1 and 2 revealed that overall ferromagnetic MII ··· MII exchange interactions exist in both complexes. |
