Modelling of the DH-II structure. (a) The DH-I unit cell is doubled and transformed (without changing the DH-I structure) into a setting comparable to that for AH. (b) One polymeric ribbon is shifted by ½b (red = before shift; blue = after shift), and the naphthalene rings are rotated to emulate the orientation in AH.
