13 C and 195 Pt spin‐lattice relaxation times, T 1 , have been determined for tetra‐ n ‐butylammonium trichloro‐pyridineplatinate(II) in different solvents. Correlation times for internal rotation around the PtN bond and for the overall motion are calculated based on a two‐site random jump model for the internal rotation. The results indicate that the ion pair forms molecular aggregates or stacks in low dielectric solvents. 13 C T i values for tetra‐n‐butylammonium trichloro(2‐propylpyridine)platinate(II) indicate that internal rotation around the PtN bond also takes place in this compound.
