Combination of Argentophilic and Perfluorophenyl-Perfluorophenyl Interactions Supports a Head-to-Head [2+2] Photodimerization in the Solid State

Face-to-face perfluorophenylperfluorophenyl interactions (C6F5 center dot center dot center dot C6F5) are achieved in a disilver metalorganic complex. The C6F5 center dot center dot center dot C6F5 interactions along with argentophilic forces support trans-pentafluorostilbazole to undergo a head-to-head [2 + 2] photodimerization to form a cyclobutane that sustains a fluorinated two-dimensional metalorganic framework.
