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

Face-to-face perfluorophenyl–perfluorophenyl interactions (C 6 F 5 ···C 6 F 5 ) are achieved in a disilver metal–organic complex. The C 6 F 5 ···C 6 F 5 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 metal–organic framework.
