The crystal packing of 4-benzyloxyindole (1) along the a axis (top left), N-2-propyl-α-oxo-4-(phenylmethoxy)-1H-indole-3-acetamide (2) along the b axis (top right), 4-benzyloxy-N-isopropylammonium chloride (3a) along the a axis (bottom left), and 4-hydroxy-N-isopropyltryptamine (4) along the a axis (bottom right). The hydrogen bonds (Tables 2–4) are shown as dashed lines. Hydrogen atoms not involved in hydrogen bonds are omitted for clarity. |
