Basic Chemistry Practice Test: Chemistry of Coordination Compounds — Flashcards

Coordination chemistry is a branch of inorganic chemistry that studies coordination compounds. 

Coordination compounds are molecular compounds made up of two or more simple molecular compounds. They are made when one or more ligands donate lone pairs to a transition metal, forming a dative bond. 

Coordination compounds are made up of the following components:
A ligand
A central atom
A complex ion
A cation
An anion 

Coordination compounds can be positively, negatively, or neutrally charged. They can also be made up of complex anions and simple cations, complex cations and simple anions, or complex anions and complex cations. 
Coordination compounds can also exhibit coordination isomerism, which is a type of structural isomerism. In coordination isomerism, the chemical formula of the isomers remains the same, but their coordination or bonding changes. 
Polynuclear complexes are coordination compounds that contain two or more metal atoms or ions in a single coordination sphere. The two atoms can be held together through direct metal-metal bonds, through bridging ligands, or both. 
Heteroleptic complexes are chemical compounds that contain at least one different ligand attached to the metal center
