Since the discovery of Zeise’s salt, K[Pt(Z -C 2 H 4 )Cl 3 ], the first organometallic complex
of a t ransition element, and particularly since the first reported s ynthesis o f f errocene,
5
[Fe(Z -C 5 H 5 ) 2 ], the number and variety o f o rganometallic compounds with unsaturated
organic ligands has increased enormously.
Complexes c ontaining ligands which coordinate to a c entral atom with at least two adjacent
atoms in a ‘ side-on’ f ashion require a s pecial nomenclature. These ligands normally contain
*The symbol ‘ ’ i s u sed to divide the name, necessitated by the line break. In the absence of the line

break this symbol is omitted. Note that all hyphens are true parts of the name.
