Figure 8
A partial packing view of (B) showing a chain structure. The intermolecular O—H⋯O hydrogen bonds (yellow lines) link the enantiomers alternately, generating C(9) chains. In the chain, further intermolecular weak C—H⋯π interactions (black dashed lines) are also observed. Cg2 is the centroid of the C27–C32 phenyl ring. Only H atoms involved in hydrogen bonds are shown for clarity. [Symmetry codes: (i) x + $[{1\over 2}]$ , −y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (iii) x − $[{1\over 2}]$ , −y + $[{1\over 2}]$ , z − $[{1\over 2}]$ .]
