Schiff bases are important systems in asymmetric catalysis [1] and their transition metal complexes can often mimic biological sites; they are therefore of great interest as enzyme models [2]. When growing crystals from solution, the solvent used sometimes plays a role in determining the crystal structure that is obtained [3]. This role can range from influencing the polymorph that is grown to being built in into the crystal structure itself to form a solvate. In this study, we synthesized a novel mercury complex using Schiff base namely 2- pyridinecarbaldehyde isonicotinoyl hydrazone (HL), described the IR, X-ray crystal structures of this compounds.
