A complex of platinum and the tetra-coordinate chelating ligand, R, R'-6, 6'-dimethyl-N, N'-bis (2'-pyridine-carboxamide) -1-cyclohexane (Me-BPCH) is investigated as a potential candidate for measurement of parity violation (PV) in chiral molecules. The synthesis of Pt (Me-BPCH) is presented alongside computational investigation of PV sensitivity in its vibrational spectrum. Pt (Me-BPCH) is compared to other two derivatives of this complex, Au (Me-BPCH) and Pt (CF₃-BPCH) in terms of their PV response and suitability for measurement. We identify the most promising vibrational transitions based on their enhanced PV effects and practical experimental considerations and analyze the relationship between the vibrational structure and the corresponding PV sensitivity for all three molecules.
