In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Multinuclear Ag Clusters Sandwiched by Pt Complex Units: Fluxional Behavior and Chiral-at-Cluster Photoluminescence, published in 2021-05-10, which mentions a compound: 12080-32-9, mainly applied to silver cluster platinum complex fluxional rearrangement isomerization chiral luminescence; crystal structure mol silver cluster sandwiched platinum preparation optimized; Ag cluster; Pt complex; fluxional behavior; photoluminescence; sandwich complex, Recommanded Product: Dichloro(1,5-cyclooctadiene)platinum(II).
Multinuclear Ag clusters sandwiched by Pt complex units were synthesized and characterized by single crystal X-ray diffraction and NMR studies. The sandwich-shaped multinuclear Ag complexes showed two different types of fluxional behavior in solution: rapid slippage of Pt complex units on the Ag3 core and a reversible demetalation-metalation reaction by the treatment with Cl anion and Ag ion, resp. The Ag2 complex obtained by demetalation reaction from the Ag3 complex displayed U to Z isomerization. These multinuclear Ag complexes showed strong photoluminescence whose properties depended on the existence of Pt→Ag dative bonds. The Ag3 complex, identified to be “”chiral-at-cluster””, was optically resolved by the formation of a diastereomeric salt with a chiral anion. The enantiomers show CD (CD) and circularly polarized luminescence (CPL) properties which is unprecedented for compounds based on a chiral sandwich structure. Theor. calculations allow to understand their structural features and photophys. properties.
This literature about this compound(12080-32-9)Recommanded Product: Dichloro(1,5-cyclooctadiene)platinum(II)has given us a lot of inspiration, and I hope that the research on this compound(Dichloro(1,5-cyclooctadiene)platinum(II)) can be further advanced. Maybe we can get more compounds in a similar way.
