The crystal structures are reported for three heterometallic Ni2Ln and a Ni2Dy2 complex, using the Schiff base ligand 2-methoxy-6-[(E)-phenyliminomethyl] phenol. Detailed dc and ac magnetic susceptibility studies were reported for all the complexes. The complexes 3 and 4 shows frequency dependent out-of-phase susceptibility signals.

Three Dy4 clusters based on a flexible and attractive Schiff base ligand HL have been synthesized, and they showed different tetranuclear core arrangements. Magnetic studies reveal that clusters 1–3 display distinct slow relaxation of magnetization.
