Silver- and Gold-Complexes Containing a new 1,10-Phenanthroline Analogue N-Heterocyclic Carbene: A Combined Structural, Theoretical and Photophysical Study
Sprache des Titels:
Unusual coordination for gold: An imidazolium salt was synthesized and used as a precursor for an N-heterocyclic carbene, which can be considered as the carbene analogue of 1,10-phenanthroline. Like the diimine congener, this ligand gives luminescent metal complexes. Remarkably, the AuIII complex features a gold atom in an unusual environment: it is surrounded by six donor atoms, two of which interact electrostatically with the Au atom (see figure).
