The molecular and crystal structures of a series of fluoro-aniline complexes of general formula trans-[PdCl2(NH2ArF)2], with ArF = C6H3-2,3-F2 (1), C6H3-2,5-F2 (2), C6H3-3,4-F2 (3), C6H3-3,5-F2 (4), C6H2- 2,3,4-F3 (5), C6H2-2,4,5-F3 (6), C6H2-2,4,6-F3 (7), were determined. Analysis of these structures demonstrate that robust reliable supramolecular synthons are obtained through Pd−N−H···Cl−Ph hydrogen-bond interactions. The possible influence of the polarization of the different ArF aromatic rings in the arrangement of the molecules within the hydrogen-bonded structures is discussed.
