with a pseudo three-coordinate Cu(I) cation. Compound 11 has a second weaker π-interaction resulting in a distorted tetrahedral geometry. Steric hindrance between the olefin and H-dpa manifests as both a twisting of the olefin out of the plane of the H-dpa ligand and a concomitant folding of the H-dpa ligand. The shifts in the νN-H IR spectral band for H-dpa ligand are consistent with the formation
