The packing of compound B viewed down the a axis. The tape structure is on the c axis line of the unit cell, depicted as overlapped molecules including a pair of O—H⋯O hydrogen bonds (yellow dotted lines). Black dashed lines indicate the intermolecular C—H⋯O and C—H⋯π interactions. Only H atoms involved in hydrogen bonds are shown for clarity.
