Solid‐state NMR Spectroscopy of Iodine(I) Complexes

Abstract

AbstractSolid‐state NMR has been applied to a series of Barluenga‐type iodine(I) [L‐I‐L]PF6 (L=pyridine, 4‐ethylpyridine, 4‐dimethylaminopyridine, isoquinoline) complexes as their hexafluorophosphate salts, as well as their respective non‐liquid ligands (L), their precursor silver(I) complexes, and the respective N‐methylated pyridinium and quinolinium hexafluorophoshate salts. These results are compared and contrasted to the corresponding solution studies and single‐crystal X‐ray structures. As the first study of its kind on the solid‐state NMR behavior of halogen(I) complexes, practical considerations are also discussed to encourage wider utilization of this technique in the future.
