The heptanuclear cobalt cluster [Co 7 (emmp) 6 (CH 3 O) 6 ] · (ClO 4 ) 2 ( 1 ) (Hemmp = 2‐ethyliminomethyl‐6‐methoxy‐phenol) was synthesized by the microwave‐assisted reaction of Co(ClO 4 ) 2 · 6H 2 O with 3‐ethoxy‐2‐hydroxy‐benzaldehyde (Hehb) and ethylamine in mixed solvent (acetonitrile:methanol = 1:1). Complex 1 was characterized by IR spectroscopy, elemental analysis, and X‐ray single‐crystal diffraction. The magnetic properties of 1 are discussed. Complex 1 displays dominant ferromagnetic interactions from the nature of the binding modes through μ 3 ‐OCH 3 and μ 2 ‐phenoxo.
