Habits of typical crystals of the 1:1 compound of rac-1,2-CHD with triphenylphosphine oxide. The largest face has been labeled as ( 0 1)T rather than as (1 0 0)T, because the latter choice leads to obvious re-entrant angles when the twinning operation (a twofold axis parallel to aT or a mirror perpendicular to that axis) is introduced. |
