Graphical Abstract

A remarkably anisotropic structure is exhibited by [Cu₂₆(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.

28aCrystal structure analysis for [Cu₂₆(hfac)₁₁(1-pentynyl)₁₅]: Crystals were grown by slow cooling of a supersaturated solution of the complex in hot n-hexane and were analyzed with a Bruker smart APEX CCD area detector equipped with an Oxford Cryosystems LT device operating at 150 K. C₁₃₃H₁₁₅Cu₂₆F₆₆O₂₂, λ=0.71073 Å, crystal size=0.44×0.38×0.29 mm, cell determination: range 4°<2θ<58°, no. reflections: 4764, monoclinic, space group Cc (checked with MISSYM^[28b-d]), Z=4, a=26.009(3), b=21.114(2), c=31.078(4) Å, β=94.214(2)^o, V=17 021(3) Å³, ρ_calcd=1.943 g cm⁻³, μ=3.300 mm⁻¹. 75 941 reflections were collected in the range 1.31°<θ<28.94 °, of which 38 578 were unique and 33 027 had F_o>4σ(F_o). A multiscan absorption correction was applied using Sadabs^[28e] (T_max=0.862; T_min=0.679). The structure was solved by direct methods (SHELXS-97),^[28f] and refined by block-matrix least-squares against F² (SHELXTL97).^[28f] All non-hydrogen atoms were modeled with anisotropic displacement parameters, except for one half-occupancy hexane solvate molecule, and H atoms were included in ideal positions. Numerous CF₃ groups were disordered, a combination of similarity and ADP equalization restraints were used to model this. The conventional R₁ factor (F_o>4σ(F_o)) was 0.0409 and wR₂ was 0.0913. (w=1/[σ²(F) + (0.0490 P)²] where P=(F + 2 )/3). Largest max/min residual electron density: +1.094/−0.917 e Å³;

37The closest Cu⋅⋅⋅Cu contacts formed by atoms in the “bud unit” (Figure 1) are either longer than the sum of van der Waals radii of two Cu^I atoms or, for Cu(24)⋅⋅⋅Cu(11) and Cu(24)⋅⋅⋅Cu(25), close to this value (2.7401(9) Å and 2.7057(10) Å respectively).
