C—H⋯O hydrogen bonding in (I)

, as viewed down [010]. The central chain interacts with four surrounding chains through C8—H8⋯O3 interactions at O3ⁱⁱⁱ, O3^iv, C8^v and C8^vi. The trace of the ( $[\overline{1}]$ 04) plane is vertical and only one molecule from each surrounding chain is shown for clarity. H atoms not involved in hydrogen bonding have also been omitted. [Symmetry codes: (i) −x + 2, −y + 1, −z + 1; (ii) −x − 1, −y + 1, −z; (iii) x + $[{1\over 2}]$ , −y + $[{1\over 2}]$ , z + $[{1\over 2}]$ ; (iv) −x+ $[{3\over 2}]$ , y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (v) x − $[{1\over 2}]$ , −y + $[{1\over 2}]$ , z − $[{1\over 2}]$ ; (vi) −x − $[{1\over 2}]$ , y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ .]
