Chemistry I Structures and Isomers

Coordination compounds are composed of a metal atom or ion and one or mo (atoms, ions, or molecules) that donate electrons to the metal. This definitioi compounds with metal-carbon bonds, or organometallic compounds, deSw . .. Chapters 13 to 15. 

Coordination compound comes from the coordinate covalent bond, which historically was considered to form by donation of a pair of electrons from one atom to another. In coordination compounds the donors are usually the ligands, and the acceptors are the metals. Coordination compounds are examples of acid-base adducts (Chapter 6), frequently called complexes or, if charged, complex ions.
