To draw link nodes, follow the steps below.
Alternatively, link nodes can be drawn in the following way:
The Link Node submenu is available through the Atom menu as well.
If it is not possible to create a link node for the specified configuration (for example, at ring fusions) MarvinSketch displays an error message. Outer (non-repeating) bonds are denoted by brackets crossing them and the repetition numbers are put on the atom. All portions of the molecule connected to the link atom through non-outer bonds are supposed to repeat together with the atom. See the table below for examples.

To edit a link node repetition number or change outer bonds, repeat the drawing steps above. To change a link atom into an ordinary atom again, select Off from the Link Node submenu or just simply overwrite it.
