Cr—C distances range from 2.177 (5) to 2.208 (4) Å in the cation and from 2.234 (4) to 2.265 (5) Å in the anion; Cr—Cl distances in the anion fall in the range 2.320 (1)–2.331 (1) Å....

(2)was found to be 17 mus,while the lifetime for Crbeta)was found to be 100 us.These values are a consequence of an energy transfer process.This energy transfer through the supramolecular interactions of the cation and anion via hydrogen bonding is probably responsible for the optical ...
