Figure 1
Anisotropic displacement ellipsoid plot of 1, drawn at the 50% probability level with H atoms omitted. Symmetry-equivalent atoms (`A' label) were generated by inversion (−x, −y + 1, −z + 1). The K2Cu2 core is asymmetric (Å): Cu1⋯K1 = 3.6637 (15), Cu1⋯K1A = 3.3762 (9), and Cu1⋯Cu1A = 2.6172 (7). |
