Figure 7
Two fragments of the structure of 3, which depict one-dimensional Cs–π chains along the b-axis direction and their aggregation through reciprocal Cs—N bonds (a) and Cs—O bonds (b) leading to the generation of the infinite NO₂/NO₂ stack. [Symmetry codes: (ii) −x, y − $[{1\over 2}]$ , −z + 1; (iv) x + 1, y, z; (vi) −x, y + $[{1\over 2}]$ , −z + 1; (ix) x, y + 1, z.]
