Hydrogen-bond dimers in the crystal structure of 3-II. Dashed lines represent hydrogen bonds. The numbers after the underscore indicate crystallographically unique molecules 1 and 2. Carbon-bound H atoms have been omitted for clarity. [Symmetry codes: (i) −x, −y + 1, −z + 1; (ii) −x + 1, −y, −z.] |
