The behavior in solution of the dicyanoaurate anion in the presence of other metal centers has so far been little explored, despite its importance in material science. The design and synthesis of systems with controlled coordination behavior, using chelating ligands and ZnII, has allowed us to detect self-assembly and oligomerization in solution This phenomenon has been studied with 13C and 1H NMR, absorption and emission UV-vis spectroscopy, ESI-MS, and XAS at both the Au L3-edge and Zn K-edge: all of these techniques confirm the presence of Au-Zn aggregation products. These fragments, resembling structural units in the solid state, reveal that coordination of dicyanoaurate to free sites around metal centers can occur at a lower concentration than those at which crystals start to form and at which aurophilic interactions are observed, forming the connection between solution species and solid-state architectures. Through the use of a multitechnique approach, the solution chem. of dicyanoaurate in the presence of zinc complexes has been successfully correlated to prenucleation aggregation. The difference in polarity or hydrogen bond properties of the crystallization solvent generates, in the presence of the same reagents, substantially different compounds, and these phases have been analyzed through the results obtained in solution
This literature about this compound(1762-34-1)Category: benzodioxanshas given us a lot of inspiration, and I hope that the research on this compound(5,5′-Dimethyl-2,2′-bipyridine) can be further advanced. Maybe we can get more compounds in a similar way.
