Polydentate-ligand-supported self-assembly of heterometallic T-shaped Co4Dy cluster showing slow magnetic relaxation

A novel mixed-valent heterometallic pentanuclear CoⅢ3CoⅡDyⅢ cluster has been rationally assembled taking advantage of a bifunctional ligand with o-vanillin and tripodal tris（hydroxymethyl）aminomethane units. This unique heterometallic cluster represents a rare example of T-shaped molecules exhibitin...

Zusammenfassung:A novel mixed-valent heterometallic pentanuclear CoⅢ3CoⅡDyⅢ cluster has been rationally assembled taking advantage of a bifunctional ligand with o-vanillin and tripodal tris（hydroxymethyl）aminomethane units. This unique heterometallic cluster represents a rare example of T-shaped molecules exhibiting slow magnetic relaxation.
