chemaxon.struc.Sgroup

chemaxon.struc.sgroup.MulticenterSgroup

All Implemented Interfaces:

java.io.Serializable

@PublicAPI
public class MulticenterSgroup
extends Sgroup

Multicenter S-group to represent complexes like markush ring structures, ferrocenes, metallocenes...
This sgroup represents a group of atoms with an atom called central atom. The atomic number of this central atom is MolAtom.MULTICENTER. The represented atoms are in the sgroup graph. Only the parent molecule of the sgroup contains the central atom, the sgroup graph doesn't.
