A remarkably anisotropic structure is exhibited by [Cu 26 (hfac) 11 (1‐pentynyl) 15 ] (hfac=hexafluoroacetylacetone), the largest Cu I cluster to have been isolated (see picture). A variety of copper–alkynyl bridging modes are found within the disc‐shaped cluster, with all but one of the 26 Cu atoms being located in either of two “layers”. Many short Cu I ⋅⋅⋅Cu I interactions can be discerned within the cluster.
