Quantum mechanical study of the kinetics, mechanisms and thermodynamics of the gas-phase decomposition of Pb[(iPr)2PSSe]2 single-source precursor

The decomposition of (iPr)PSSe-Pb intermediate formed from Pb[(iPr)2PSSe]2 precursor involves three pathways: dissociation of iPrS− anion, dissociation of iPrSe− anion and heterogeneous P-S and P-Se bond cleavages. The heterogeneous dissociation of P-S and P-Se bonds is the slowest step in the reaction mechanism.
