The research presents a new synthetic strategy for creating multinuclear aggregates containing a {Pt2S2}n core. The key chemicals involved in this research include [(dppp)Pt(μ-S)2Pt(dppp)], [PtCl2(PhCN)2], and Na2S·9H2O. The synthesis begins with the reaction of [(dppp)Pt(μ-S)2Pt(dppp)] with [PtCl2(PhCN)2] to form the compound [{Pt2(μ3-S)2(dppp)2}PtCl2]. The chloride ligands in this compound are labile and can be replaced by bridging sulfide ligands, facilitated by the addition of Na2S·9H2O, leading to the formation of more complex multinuclear structures such as [{Pt2(μ3-S)2(dppp)2}2{Pt2(μ-S)2}] and [{Pt2(μ3-S)2(dppp)2}Pt2(μ3-S)2PtCl2{Pt2(μ3-S)2(dppp)2}]. The study also involves the characterization of these compounds using techniques like NMR spectroscopy, ESI-MS, and MALDI-TOF mass spectrometry, and computational methods to understand the thermodynamic feasibility of the reactions. This work provides valuable insights into the synthesis and properties of multinuclear platinum-sulfide complexes, which have potential applications in various industrial and chemical processes.

The research investigates the synthesis, structure, and reactivity of organoantimony(III) and organobismuth(III) sulfides containing O,C,O-chelating ligands. The study involves the preparation of these compounds by reacting parent organoantimony and organobismuth chlorides with Na2S·9H2O in a toluene/water mixture. The resulting sulfides were characterized using elemental analysis, electrospray ionization mass spectrometry, 1H and 13C NMR spectroscopy, and X-ray diffraction techniques. The stability of these compounds was examined, with organoantimony sulfides showing stability at room temperature, while the organobismuth analog required storage at -30 °C. The study also explored the reactions of these sulfides with iodine, yielding expected diiodides and an unexpected oxastibol compound. The chemicals that played a crucial role in this research include the starting materials such as organoantimony and organobismuth chlorides (L1-3MCl2), Na2S·9H2O, and iodine. The ligands used were 2,6-(ROCH2)2C6H3- where R is Me (L1), t-Bu (L2), or mesityl (L3). The solvents used for the reactions and characterizations were toluene, water, and chloroform. The study provides valuable insights into the structural and reactivity properties of these organometallic compounds.
