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.

This unique heterometallic cluster represents a rare example of T-shaped molecules exhibiting slow magnetic relaxation.
