With regard to its electronic structure, the cation Icoll(2)(+) (coll = collidine or 2,4,6-trimethylpyridine) is viewed as a coordination compound of iodine(I) with a p(4) electron configuration. The lowest-energy excited state of Icoll(2)(+) is suggested to be a pipi* collidine intraligand (IL) triplet which appears in absorption (lambda(max) = 332 nm, epsilon = 250) and emission (lambda(max) = 405 nm, phi = 0.001, tau similar to 90 ns). Owing to the heavy-atom effect of iodine this phosphorescence occurs at r.t. The longest-wavelength pp absorption is apparently obscured by the intense spin-allowed IL band at lambda(max) = 268 nm.
