Bimetallic neutral palladium (II) bis(dithiolene) complex: Unusual synthesis, structural and theoretical study
چکیده انگلیسی

The unusual synthesis of the dimeric dithiolene complex [(PPh3)Pd(ethylene-1,2-dithiolate)]2 (1), containing the simplest dithiolene ligand, has been achieved through the reaction between tetrathiafulvalene (TTF) and Pd(PPh3)4. The complex shows a folded structure in the solid state, according to single crystal X-ray analysis performed on crystals grown from two different system solvents and conditions, with a central [Pd2S2] ring folded about the S···S hinge by 67.9°. The optimized geometry at the DFT level is in excellent agreement with the experimental structure. Moreover, TD-DFT calculations allowed the assignment of the low energy band arising at 576 nm to the HOMO→LUMO transition, between frontier orbitals having mixed metal and dithiolene character.
