Figure 4
A stereoview of part of the crystal structure of (IV) (CSD refcode SILTEN; Dong & Huang, 2007), showing the formation of a hydrogen-bonded sheet parallel to (101) containing rings of R22(6), R22(8) and R66(40) types. The original atom coordinates have been used (Dong & Huang, 2007). For the sake of clarity, H atoms bonded to C atoms have all been omitted. Hydrogen bonds are indicated by dashed lines. |
