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