In this article, we examined different synthetic approaches with varying adding starting materials for the thiol containg schiff-base complex [ZnL1]2(L1=o-C6H4(SH)(CH=NC6H4SH-o)). We found that the key step for successful synthesis of [ZnL1]2 is the formation of zinc aldehyde intermediate. We also break the [ZnL2]2 dimer by adding chelating agent, TMEDA, to obtain the Zn(L1)(TMEDA) monomer. It¡¦s single crystal X-ray structure confirmed, the structure of the target ligand L1. We also synthesized [NiL1]2 by transmetalation of [ZnL1]2 - an easier synthetic approach. We further reduced the imine part on L1 of [ZnL1]2 and Zn(L1)(TMEDA) to get [ZnL2]2(L2=o-C6H4(SH)(CH2NHC6H4SH-o)) and Zn(L2)(TMEDA) respectively for future reactivity studies.
