J. Breu et al., ARENE-ARENE STACKING IN CIS-BIS[2-(2-THIENYL-C-3)PYRIDINE-N]PLATINUM(II), Acta crystallographica. Section C, Crystal structure communications, 53, 1997, pp. 562-565
In the crystal structure of the title complex, [Pt(C9H6NS)(2)], althou
gh the aromatic ligands are coordinated to a central heavy metal stem.
T-shaped and shifted pi-stacked arrangements of the aromatic moieties
are preferred, leading to a sandwich herring-bone type of crystal-pac
king motif. The crystal structure is therefore consistent with the vie
w that the arene-arene interactions are determined by electrostatics (
multipole-multipole).
