Pyridine–pyridine π–π stacking interactions in pentacarbonyl[pyridine-4(1H)-thione]tungsten(0)
摘要:
In the title compound, [W(C5H5NS)(CO)(5)], the pyridine-4-thiol ligand coordinates through the sulfur in the thione mode. The coordination sphere around the W atom is distorted from octahedral geometry by intermolecular hydrogen bonding and steric interactions between the pyridine ring and two CO ligands. An intermolecular pyridine-pyridine ring distance of 3.47 (1) Angstrom indicates pi-pi stacking interactions between these ligand units.
