along the a axis of the unit cell; only the H atoms involved in the weak interactions have been included. In this orientation, the atom O3 in position 1 − x, −y, 1 − z is exactly superimposed on the O3 atom in position −x, −y, 1 − z, which interacts with C33—H33. The molecule in position −x, −y, 1 − z is not shown for clarity.
