Abstract

The analysis of the crystal structures of two new mononuclear Pd(II) compounds, containing 3,5-disubstituted-2-(2'-pyridyl)pyrrole ligands, reveals that the use of fluoroaliphatic (1) versus aliphatic (2) substituting groups on the HLn ligand induces substantial changes in their supramolecular architectures. Despite the common molecular geometry suitable for the formation of mixed "aryl embraces", "tetris-like" columnar heterochiral (1) and helicoidal chiral (2) organizations are formed. The resulting supramolecular packing affects their solid state photophysical properties.
