Calculations. TDDFT, NBO, NPA, LOL, simulation of Raman spectra analyses were performed using the Gaussian16 program package. Quantum theory of atoms in molecules (QTAIM) analysis was performed in the AIMAll package. The molecular structure of the model is made from the crystal structure of 1, 2 and simplified using GaussView5.0. The B3LYP functional was used with Def2-SVP (for C, H), 28a Def2-TZVP (for S, O), 28a Def2-TZVPD (for Pt) with ECP, 28b
