文摘

The chiral dodecanuclear palladium(II) thio cluster LaPd₁₂(C₃H₅NO₂S)₃(C₃H₆NO₂S)₂₁ (1) was prepared by reacting l-cysteine (l-Cys) with PdCl₂ and La₂O₃ in aqueous solution under carefully controlled conditions. Compound 1 was structurally characterized by single-crystal XRD, TGA, IR, UV–vis, ¹³C NMR, and CD spectroscopy. Insight into the dimerization process of 1 was obtained by ESI-MS and DFT calculations.
