• A new, unusual trichlorocadmate complex of cadmium has been prepared.
• A NMR and ESI-MS analysis has been performed to study the anion stability.
• His stability relies on crystal packing forces.
The complex [Ag(PPh3)4][(PPh3)CdCl3] was synthesized and its crystal structure was determined. Solid state properties of the complex were further studied by 31P SS-NMR, Raman and IR spectroscopies. This compound presents one of the rare cases of monomeric trichlorocadmate, the first reported with a phosphorus ligand. We can obtain this thanks to the use of a big spherical cation like [Ag(PPh3)4]+. In the same time we analyze the structural effects that govern the crystallochemistry of analogous compounds. The absorption and emission properties of this compound in the solid state were analyzed by a computational modeling. For the rarity of the complex, we use the ESI-MS and 31P NMR techniques to check the properties of this anion in ethanolic solution, and the results are useful to evaluate the stability of [(PPh3)CdCl3]− ion and the role of [Ag(PPh3)4]+ ion in organizing the crystal structure during the crystal growth.
The bulky pseudo-spherical [Ag(PPh3)4]+ ion is able to stabilize in the solid state the [(PPh3)CdCl3]− complex.Figure optionsDownload as PowerPoint slide
