Figure 3
A partial packing diagram viewed down the a axis, showing the tape structure running along the b-axis direction. Yellow lines indicate the O—H⋯O hydrogen bonds. Black dashed lines indicate C—H⋯O interactions. Only H atoms involved in the hydrogen bonds are shown for clarity. [Symmetry codes: (i) x − 1, y, z; (ii) −x + 2, y − , −z + ; (v) x − 1, y + 1, z.] |
