Abstract
A new ligand 3’,4’-bis(2-iminomethyl phenol)-2,2’:5’,2’’-terthiophene(L), has been
synthesized by condensation of 3’,4’-diamino-2,2’:5’,2’’-terthiophene and
salicylaldehyde. The Ni(II) and Zn(II) complexes of the ligand were synthesized and
characterized on the basis of their spectral (IR, NMR, UV-Vis, AAS, MS), molar
conductivity and magnetic susceptibility measurements, and based on this the structures
of both the complexes were octahedral. The ligand behaves as neutral ONS-ONS bischelant
towards Ni(II) in [Ni2LCl4(H2O)2]. 4H2O and as dibasic ONNO donor towards
Zn(II) in [ZnL(NH3)2]. The participation of ring sulfur in bonding towards Ni(II) and the
non-participation of the ring towards Zn(II) are notable features.
Key words: 3’,4’-bis(2-imino methyl phenol)-2,2’:5’,2’’-terthiophene, 3’,4’-Diamino-
2,2’:5’,2’’-terthiophene, salicylaldehyde, Ni(II) and Zn(II) complexes
