Abstract

Cyclic trinuclear Ag(I) pyrazolate interacts with phenylacetylene forming a mix-ligand complex in which one pyrazolate ligand is changed to phenylethynide. The C[triple bond, length as m-dash]C− fragment coordinates only to two silver(I) atoms via one carbon atom demonstrating unique μ2-η1 σ-coordination with close Ag–C bond lengths and Ag–C–C angles. The complex exhibits blue emission under UV irradiation.
