Inorganic Nomenclature

This document provides information about ligands and prefixes used in naming coordination complexes. It lists common ligands such as halides, oxoanions, neutral ligands, and organometallic ligands. Prefixes are used to indicate the number of ligands bound to the central metal atom. The document also provides rules for naming anionic complexes based on the metal and ligand present.
