摘　　要：A novel mixed-valent heterometallic pentanuclear CoⅢ3 CoⅡ Dy Ⅲ 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.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.
