The bis-benzimidazolium salt bis[2-(N-ethylbenzimidazoliumyl)ethyl]amine hexa- fluorophosphate (LH₂·(PF₆)₂) and its N-heterocyclic carbene silver(I) complex [L₂Ag₃](PF₆)₃ (1) have been prepared and characterized. In complex 1, a trinuclear silver(I) architecture is formed by two tridentate ligands and three silver(I) atoms, in which one 12- and two 7-membered rings are contained. In the crystal packing of 1, 1D chain and 2D supramolecular layer are formed via intermolecular weak interactions, including π…π interactions and C-H…π contacts. Additionally, the fluorescence emission spectra of LH₂·(PF₆)₂ and 1 are described.
