Abstract

Three novel clusters, [Ag3L2][BF4]3, [Au2L2][BF4]2 and [Au2Ag2L2(MeCN)2][BF4]4 have been assembled on the platform of tris[(6-methylpyridin-2-yl)methyl]phosphine (L). The obtained clusters feature the pronounced Ag∙∙∙Ag and Au∙∙∙Au metallophilic interactions (dM–M = 2.90–3.06 Å) proved by both crystallographic data and QTAIM analysis. Moreover, the clusters {Au2} and {Au2Ag2} appear to emit a weak solid-state room temperature phosphorescence with λmax = 435 and 530 nm, respectively.
