Thiopyridazine-Based Palladium and Platinum Boratrane Complexes

Area of Science:

• Organometallic Chemistry
• Inorganic Chemistry

Background:

• Palladium and platinum complexes are crucial in catalysis and materials science.
• Boratrane ligands offer unique coordination properties.

Purpose of the Study:

• To synthesize and characterize novel palladium and platinum boratrane complexes.
• To investigate the electronic properties and metal-ligand interactions within these complexes.

Main Methods:

• Reaction of potassium tris(4-methyl-6-tert-butyl-3-thiopyridazinyl)borate (KTnMe,tBu) with metal precursors.
• Spectroscopic characterization (NMR, IR).
• X-ray crystallography and Density Functional Theory (DFT) calculations.

Main Results:

• Synthesis of palladium and platinum boratrane complexes, including symmetric boratranes, hydrido, and dihalide compounds.
• Characterization revealed strong metal-boron interactions.
• DFT calculations confirmed significant M-B bonding and positive charge on metal centers.

Conclusions:

• The study successfully synthesized and characterized a series of novel palladium and platinum boratrane complexes.
• Strong metal-boron interactions and significant positive charge on the metal centers were confirmed.
• These findings contribute to understanding the coordination chemistry of boratrane ligands with late transition metals.
