Trialkyltin Compounds

Organometallic compounds which contain tin and three alkyl groups.

Year introduced: 1975

Select item 20234103.

Metallocenes

Organometallic compounds that generally consist of two cylcopentadiene ANIONS joined in their centers by a metallic cation such as NICKEL; IRON; or TITANIUM.

Year introduced: 2018

Select item 680568314.

Coordination Complexes

Neutral or negatively charged ligands bonded to metal cations or neutral atoms. The number of ligand atoms to which the metal center is directly bonded is the metal cation's coordination number, and this number is always greater than the regular valence or oxidation number of the metal. A coordination complex can be negative, neutral, or positively charged.
