Figure 4
Hydrogen-bonding inter­actions in the form I polymorph. Mol­ecules are linked into infinite chains that extend along the c-axis direction. Hydrogen-bonded mol­ecules are symmetry-related to each other via the 41-screw axis of the I41/a space group. Coordinates from Wang et al. (2020BB20). Displacement ellipsoids are shown at the 50% probability level. H atoms not involved in hydrogen-bonding are omitted for clarity.
