Abstract
The crystal structures of several [Cu(RCN)4]X salts (R = Me, X = SO3CF3 −; R = Ph, X = BF4 −, ClO4 −, and PF6 −) were determined using single crystal X-ray diffraction. All of the compounds contain distorted tetrahedral Cu(I) centers and noncoordinating anions, with the acetonitrile and benzonitrile structures containing three and one unique CuL4 + complex in their respective asymmetric units. One important distortion is observed in the benzonitrile-Cu bonds, which are bent up to 23° away from linearity. The result is a flattened complex that maximizes the π–π tacking of the aromatic rings and is the dominant packing interactions between the complexes.

A further complication arose, in that one oxygen atom occupied virtually the same position as the carbon atom of the alternate position. Because of the similarity in scattering power of C and O (and the relatively equal occupancy) the site was refined as a fully occupied carbon atom.
All of the descriptions and pictures appearing in the manuscript will be of the ClO -4 structure. Analogous figures and crystallographic data for the BF -4 salt will be placed in the Supplementary Materials.
