. Only parts of the complex are shown for clarity. The C—H⋯O hydrogen bonds are shown as blue dashed lines. The green dashed lines indicate other O⋯H contacts shorter than 2.8 Å, O4⋯H30^v = 2.77 Å and O8⋯H37^vii = 2.66 Å. Symmetry codes: (i) x + $[{1\over 2}]$ , −y + $[{3\over 2}]$ , −z + 1; (ii) x + 1, y, z; (iii) −x, y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (iv) x − $[{1\over 2}]$ , −y + $[{3\over 2}]$ , −z + 1; (v) x − $[{1\over 2}]$ , −y + $[{1\over 2}]$ , −z + 1; (vi) −x, y − $[{1\over 2}]$ , −z + $[{1\over 2}]$ ;; (vii) −x + 1, y − $[{1\over 2}]$ , −z + $[{1\over 2}]$ .
