Abstract

Intramolecular stacking of the (4′-chloro-2,2′∶6′,2″-terpyridine)platinum( II) moieties occurs in N,S-bis[(4′-chloro-2,2′∶6′,2 ″-terpyridine)platinum(II)]-2-mercaptoimidazole tris-hexafluorophosphate; N,S-bis[(2,2′∶6′,2″-terpyridine) platinum(II)]thioacetimine trinitrate is slowly transformed in aqueous solution to the molecular propeller-like tris[(2,2′∶6′,2″-terpyridine)platinum(II )]sulfonium ion.
