Axial chirality and supramolecular interactions: The case of [(k(2)-P,P-{PPh2NMe}(2)CO)(CuCl)-Cl-I](2)
The title compound [(kappa(2)-PP-{PPh2NMe}(2)CO)(CuCl)-Cl-I](2) (4) is readily formed by the reaction between (PPh2NMe)(2)CO and copper(I) chloride. Compound 4 forms a two-dimensional supramolecular network of Cu2Cl2-centered dimers that are linked by pi-pi interaction between the phenyl substituents on phosphorus in the solid state. Because of the nature of these pi-pi interactions, only one of the three possible enantiomers, the meso form, can be observed in the crystals.
