Liste der Liganden-Abkürzungen

Auf dieser Seite werden allgemein gebräuchliche Abkürzungen für Liganden in der Chemie zusammengestellt. Als Ligand wird hier allgemein eine Gruppe von Atomen oder einzelne Atomen verstanden, die an ein zentrales Teilchen koordiniert sind. Die Abkürzungen werden im Allgemeinen in die Strukturformel mit einbezogen.

Auch Aminosäuren können als Liganden koordinieren. Diese können mit dem Dreibuchstabencode bezeichnet werden.
