A new tetranuclear mixed‐valence cobalt complex, namely di‐μ 2 ‐azido‐diazidodiethanolbis{μ 2 ‐2‐[(hydroxyimino)methyl]‐6‐methoxyphenolato}bis{μ 3 ‐6‐methoxy‐2‐[(oxidoimino)methyl]phenolato}dicobalt(II)dicobalt(III) ethanol disolvate, [Co II 2 Co III 2 (C 8 H 7 NO 3 ) 2 (C 8 H 8 NO 3 ) 2 (N 3 ) 4 (C 2 H 5 OH) 2 ]·2C 2 H 5 OH, has been synthesized by the reaction of Co(OAc) 2 ·4H 2 O (OAc is acetate) with 3‐methoxysalicylaldoxime (H 2 mosao) in an ethanol solution. In the complex, the four Co cations all display distorted octahedral coordination environments and they are bridged by two κ 2 ,κ 1 ,κ 1 ;μ 3 ‐mosao 2− ligands, two κ 2 ,κ 2 ;μ 2 ‐Hmosao − ligands and two μ 2 ‐N 3 − anions to form a tetranuclear [Co 4 N 4 O 4 ] cluster. Adjacent clusters are connected through weak C—H...N and C—H...O interactions, resulting in a two‐dimensional supramolecular network parallel to the ac plane. The magnetic properties of the complex have also been studied.
