Abstract
In the title compound, [W(C5H5NS)(CO)(5)], the pyridine-4-thiol ligand coor dinates through the sulfur in the thione mode. The coordination sphere arou nd the W atom is distorted from octahedral geometry by intermolecular hydro gen bonding and steric interactions between the pyridine ring and two CO li gands. An intermolecular pyridine-pyridine ring distance of 3.47 (1) Angstr om indicates pi-pi stacking interactions between these ligand units.
