Figure 3
Compound 1, view of the ladder of alternating linked R₂²(18) and R₂²(20) structures formed by the interaction of centrosymmetrically related pairs of C6—H6⋯O3ⁱⁱ hydrogen bonds across the centre of symmetry at (0, $[{1\over 2}]$ , $[{1\over 2}]$ ) and centrosymmetrically related pairs of C36—H36⋯O7ⁱⁱⁱ hydrogen bonds across the centre of symmetry at ( $[{1\over 2}]$ , $[{1\over 2}]$ , $[{1\over 2}]$ ). This chain extends by unit translation along the a axis. Hydrogen atoms not involved in the hydrogen bonding have been omitted.
