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.
