A motif for infinite metal atom wires

Area of Science:

• Inorganic Chemistry
• Materials Science
• Supramolecular Chemistry

Background:

• Infinite metal atom chains offer unique electronic and optical properties.
• Developing new motifs for constructing these chains is crucial for materials innovation.
• Paddlewheel and square planar complexes are established building blocks in coordination chemistry.

Purpose of the Study:

• To design and synthesize novel infinite metal atom wires.
• To investigate the structural, photoluminescent, and precursor properties of these new compounds.
• To explore the tunability of properties by varying metal ions and ligands.

Main Methods:

• Single-crystal X-ray diffraction for structural determination.
• Synthesis of palladium and palladium-platinum chain compounds.
• Characterization of photoluminescent properties.
• Evaluation as precursors for bimetallic nanostructures.

Main Results:

• Successfully synthesized two infinite palladium chain compounds and one infinite palladium-platinum heterometallic chain compound.
• Established a new motif connecting metal paddlewheel and square planar complexes via metallophilic interactions.
• Observed tunable photoluminescence in the synthesized one-dimensional metal wire compounds.
• Demonstrated the utility of compound 3 as a single-source precursor for Pd4Pt bimetallic nanostructures.

Conclusions:

• A novel structural motif for infinite metal atom wires has been established.
• The synthesized compounds exhibit tunable photoluminescence, dependent on ligand and metal composition.
• The heterometallic compound serves as a valuable precursor for controlled synthesis of bimetallic nanostructures.
