Fishnet-like layeredcompounds comprising trifluoroacetate-bridged paddlewheel dimetal(II, II) complexes and 7,7,8,8-tetracyano-p-quinodimethane (TCNQ) were crystalized with anthracene (ANT) molecules between their layers and crystallization solvents at their hexagonal columnar pores. These complexes undergo a solvent-release crystal-to-crystaltransformation involving the migration of a portion of
