Figure 3
Part of the crystal structure of (I), showing the formation of the two-dimensional framework with fused R22(8) (denoted A), R32(10) (denoted B) and R33(15) (denoted C) rings. Dashed lines indicate hydrogen bonds. [Symmetry codes: (i) x + 1, −y + , z − ; (ii) x − 1, y, z; (iii) x − 1, −y + , z + ; (iv) x, −y + , z + .] |
