Figure 3
End views of 1 (left) and 3 (right) that highlight the much greater asymmetry of the dicuprate. Representative atom–atom distances are shown (Å). In 1, the six closest C atoms to the shorter Cu⋯K contact have an average K⋯C distance of 3.14 (13) Å, while those closest to the longer Cu⋯K contact have an average K⋯C distance of 3.38 (5) Å. |
