Coordination complex

Cisplatin, PtCl₂(NH₃)₂
A platinum atom with four ligands

Grubbs' catalyst, another example of a chemical complex.

A coordination complex are molecular compounds which are formed by the combination of two or more simple salt and which retain their identity in solid as well as in aqueous form.

Susumu Kitagawa, Richard Robson and Omar Yaghi won Nobel Prize in Chemistry in 2025 for study on coordination chemistry and metal-organic flamework.
