Abstract

The nature of bonding between two metal centres is extremely variable, spanning formal bond orders from 1 to 6, and this leads to a great diversity of chemical properties in metal cluster compounds. The bonds themselves have components with σ, π, δ, and ϕ symmetry, each of which has its own distinct properties. This article reviews the key features of these different bonding components.
