The title compound [(kappa2-P,P-[PPh(2)NMe}2CO)Cu(I)Cl]2 (4) is readily formed by the reaction between (PPh2NMe)2CO 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.
