The recently-increasing interest in coinage metal clusters stems from their photophys. properties, which are controlled via heterometalation. Herein, the authors report homometallic Ag46IS13 clusters protected by octahedral fac-[Ir(aet)3] (aet = 2-aminoethanethiolate) mols. and their conversion to heterometallic Ag43IM3IS13 (M=Cu, Au) clusters. The reactions of fac-[Ir(aet)3] with Ag+ and penicillamine produced [Ag46S13{Ir(aet)3}14]20+ ([1]20+), where a spherical Ag46IS13 cluster is covered by fac-[Ir(aet)3] octahedra through thiolato bridges. [1]20+ was converted to [Ag43M3S13{Ir(aet)3}14]20+ ([1M]20+) with an Ag43IM3IS13 cluster by treatment with M+, retaining its overall structure. [1]20+ was photoluminescent and had an emission band ∼690 nm that originated from an S-to-Ag charge transfer. While [1Cu]20+ showed an emission band with a slightly higher energy of ∼650 nm and a lower quantum yield, the emission band for [1Au]20+ shifted to a much higher energy of ∼590 nm with an enhanced quantum yield.
