Penta-coordinated Zn(II) ions are considered as active sites in biologically important enzymes such as, liver alcohol dehydrogenase and carbonic anhydrase. Only a limited number of reports are in the literature regarding penta-coordinated Zn(II) or Cd(II) ions. We have synthesized two new penta-coordinated Cd(II) complexes (as poly-morphs) by reacting CdI2 with 2,6 diacetylpyridine in acetone through the process of co-crystallization. Complete structural analysis of all new compounds, both spectroscopic and single crystal x-ray diffraction analysis, will be presented. We are planning to explore the coordination chemistry analogs of 2,6-diacetylpyridine with other transition metal ions and study catalytic activities of all new metal complexes in simple organic reactions.

Role: In collaboration with my lab partners, I conducted the co-crystallization experiments that produced the crystals containing the penta-coordinated Cadmium (II) ion, helped analyze the single crystal x-ray diffraction data results, combined materials, data, and results for abstract formation and presentation.
