View of the structure approximately along [001] showing atomic numbering and the hydrogen bonding. The origin is at the upper left corner near the pair K1/K1′, the y axis is pointing to the right, x is pointing down. Displacement ellipsoids represent 50% probability. K1′ corresponds to K1ii in Table 5[link].
