Coordination Compound In this compound coordination, the central metal atoms or ions are linked with other ions or neutral molecules by coordinate bonds. These clusters are also called Complex compounds. A certain number of ions or atoms (ligands) attached to a central metal atom form a subunit or coordination power. Many metal-containing compounds, especially those of transition metals, are coordination complexes. A coordination complex whose center is a metal atom is called a metal complex. Let's know more about Coordination Compound quiz questions and answers.
