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.
