Synthesis and X-ray diffraction study of a chiral bis-phosphahelicene palladium (II) complex.

Synthesis and X-ray diffraction study of a chiral bis-phosphahelicene palladium (II) complex. Chirality. 2019 Jun 26;: Authors: Sanogo Y, Aillard P, Retailleau P, Voituriez A, Marinetti A Abstract As a complement to our previous studies on the development of a class of chiral phosphahelicenes, this article discloses the synthesis, spectroscopic, and structural characterizations of a new phosphahelicene transition metal complex. It demonstrates the ability of these hindered chiral ligands to coordinate Pd (II) in trans-complexes Cl2 Pd(L*)2 . In the solid state, the complex adopts a C2-symmetric arrangement with two ligands facing each other on the same face of the coordination plane. X-Ray data highlight bending of the Pd (II) unit from the expected planar coordination geometry that might be due to a significant π-π stacking effect between the central rings of two helical units.
