Electronic and steric impact of bis-NHC ligands on reactions of Pt3S2 cores in trinuclear complexes bearing bis-NHC ligands with various lengths of alkylene bridges

Alkylene-bridged bis-N-heterocyclic carbene ligands working as strong sigma-donors enhance the reactivity of the Pt3S2 core in a triplatinum complex. Although an Ag(i) ion possibly reacts with the Pt-Pt bond, one of the sulfide ligands coordinates to an Ag(i) ion due to the steric hindrance of the ligands.

Automated summary

The use of alkylene-bridged bis-N-heterocyclic carbene ligands enhances the reactivity of the Pt3S2 core in a triplatinum complex. Despite the potential reaction between an Ag(i) ion and the Pt-Pt bond, steric hindrance results in coordination of one sulfide ligand to the Ag(i) ion.
