Figure 2 Part of the crystal structure of (I), viewed down the b axis, showing the formation of a [0 0 1] (16) chain built from O—H⋯O hydrogen bonds. For clarity, H atoms not involved in the motifs shown have been omitted. Dashed lines indicate hydrogen bonds [symmetry codes: (*)-1/2-x,-y,1/2 + z; (#)-1/2-x,-y,- + z; (&)x,y,1 + z]. |
