Tripodal M III Complexes on Au(111) Surfaces: Towards Molecular “Lunar Modules”

A series of tripodal M III complexes (M = Ga, Mn, Fe) functionalized with three methylsulfanyl end‐groups for deposition on Au(111) were synthesized. The structures were designed to build rigid three‐dimensional molecular structures that stand on their own with multiple attachments on the metallic s...

Description
Summary:A series of tripodal M III complexes (M = Ga, Mn, Fe) functionalized with three methylsulfanyl end‐groups for deposition on Au(111) were synthesized. The structures were designed to build rigid three‐dimensional molecular structures that stand on their own with multiple attachments on the metallic surface. The coordination compounds are based on a trensal [(tris(2,2′,2"‐salicylideneimino)triethylamine)] Schiff base ligand which provides stable metal complexes. The molecular structures of Ga III , Fe III , and Mn III complexes were determined by single‐crystal X‐ray diffraction crystallography. Magnetic properties depend on the coordinated metal ion and vary from a diamagnetic Ga III complex to paramagnetic high‐spin Fe III and Mn III complexes. A submonolayer of the Ga III complex deposited on Au(111) was studied in a preliminary ultra‐high‐vacuum scanning tunneling microscopy (UHV‐STM) investigation.
