Abstract

The 3:2 Charge Transfer (CT) co-crystal (Perylene)₃(TCNQF₁)₂ is grown by the Physical Vapor Transport (PVT) method, and characterized structurally and spectroscopically. Infrared analysis of the charge sensitive modes reveals a low degree of charge transfer (less than 0.1) between donor and acceptor molecules. The crystal is isostructural to the other 3:2 CT crystals formed by Perylene with TCNQF₂ and TCNQF₄, whereas such stoichiometry and packing is not known for the CT crystals with non-fluorinated TCNQ. The analysis of the isostructural family of 3:2 Perylene– TCNQF_x (x = 1,2,4) co-crystal put in evidence the role of weak F… HC bonding in stabilizing this type of structure.
