Figure 1
The molecular structure of (I). (a) A drawing of the asymmetric unit, with displacement ellipsoids at the 25% probability level. (b) A perspective view of the zigzag ladder portion. H atoms and non-bridging cyano groups have been omitted for clarity [symmetry codes: (i) −1 − x, −1 − y, 1 − z; (ii) x − 1, y, z]. |
