A {CoII9CoIII3} dodecanuclear cluster based on o-vanillin oxime: Synthesis, structures and properties

A new dodecanuclear cluster [CoII9CoIII3(MeOsalox)6(OAc)15(H2O)6]·2MeCN·2H2O (1) (H2MeOsalox = 3-methyloxysalicylaldoxime) was synthesized under solvothermal conditions and characterized by IR, elemental analyses (EA), single-crystal X-ray diffraction and powder XRD. Magnetic investigations reveal that complex 1 exhibits antiferromagnetic interactions between the cobalt centers.

One mixed-valence cobalt(II/III) dodecanuclear cluster bridged by doubly deprotonated o-vanillin oxime and acetate anions has been assembled. Antiferromagnetic interactions between the cobalt ions are observed.Figure optionsDownload as PowerPoint slide
