Hydrogen bond network in the crystal lattice of 2. The Etter notation for the lower-level nets are indicated in the blue lettering: $D_{1}^{1} (2)$ a; $D_{1}^{1} (2)$ b; $D_{1}^{1} (2)$ c; $D_{1}^{1} (2)$ d; $C_{2}^{2} (6)$ > a < b; $C_{2}^{2} (8)$ > a < c; $C_{2}^{1} (6)$ > a < d; $C_{2}^{1} (6)$ > b < c; $R_{2}^{2} (8)$ > b < d; $C_{2}^{2} (6)$ > c < d. The relative H-bond strengths are color-coded, with yellow being stronger than orange.
