Abstract
This work describes the synthesis, and structural, spectroscopic, and theoretical studies of a mononuclear silver(I) complex with the formula [Ag(Xantphos)(4,4′-(MeO)2-2,2′-bipy)]BF4·DCM (1·BF4) [Xantphos: 4,5-bis(diphenylphosphino)-9,9′-dimethylxanthene]. We provide meaningful insights into the enhancement of the photoluminescence features of this silver(I) complex compared to its copper(I) analogue.
