Abstract

The combination of 4-phenyl substituted pyrazolate ligand, LEt(Ph)H (4-phenyl-3,5-diethyl-1-pyrazole) with coinage metal(I) salts gave cyclic structures, [CuLEt(Ph)]₃, {[AgLEt(Ph)]₃}₂, and [AuLEt(Ph)]₃. Both [CuLEt(Ph)]₃ and [AuLEt(Ph)]₃ were trinuclear, while {[AgLEt(Ph)]₃}₂ was hexanuclear with two intermolecular argentophilic interactions. {[AgLEt(Ph)]₃}₂ formed arene-sandwiched, π acid/base complexes, {[AgLEt(Ph)]₃}₂(mesitylene) and {[AgLEt(Ph)]₃}₂(toluene). Photoluminescent spectra of the Cu(I) and Ag(I) complexes were dominated by closed shell d¹⁰-d¹⁰ M£M interactions, whereas those of the Au(I) complex exhibited ligand-based emissions.
