Tridentate Schiff Base

A new family of mononuclear LnIII complexes were synthesized by utilizing a tridentate Schiff base ligand. SIM behaviour is seen in the DyIII analogue (diluted) with Ueff = 68(2) K under a 1000 Oe applied dc field.

Unsymmetrical Schiff Base

Five heterometallic Cu2Ln complexes (Ln = Gd, Tb, Dy, Ho and Er) have been synthesized using asymmetric Schiff base ligand. Among these, Cu2Tb and Cu2Dy complexes show field induced SMM behaviour.
