Figure 4
(a) Projection along the a axis of the spiral chain of Cu2(CN)5 and C3≡N3 units related by the 43 axis at x = 0, y = 0. Generic atom labels without symmetry codes have been used. (b) Packing diagram showing a projection along the c axis. The projection of the spiral chain shown in Fig. 4(a) is highlighted in bold. Only the cations within the unit cell are shown, with bonds drawn in green. |
