Abstract
Clusters of polylithium organic compounds, (CnLim)x, are perhaps the most interesting and unusual clusters in all of main group chemistry from a structural and reactivity point of view. These unusual clusters, such as (CLi4)3 and (CLi2H2)4, were discovered by Richard Lagow and research associates in 19821,2 thus opening this field of chemistry for years of fascinating structural investigations to follow. Compounds from first row elements in which the central element had a nearly empty 2p orbital have a very pronounced tendency to form polymeric or oligomeric clusters such as those observed and studied for the boron hydrides, (BnHm)x. This fact has been well established. The 1976 Nobel Prize in Chemistry was awarded for structural studies of the boron hydrides and boron hydride clusters. Polylithium organic compounds promise to offer an even more fascinating story from a structure and bonding point of view since the lithium electron configuration has a completely empty 2p orbital (is22s12p0) in contrast to the well known electron configuration for boron hydride (1s22s22p1). Boron hydrides are often called “electron deficient species” and if this is so, clusters of polylithium compounds have even more chances for multicenter bonding.

Refinement of this model was carried out with the soft constraint that D(1)-D(2) be separated by 1.78(25) A. This was required because of the close approach of D(1) to the twofold axis passing through the carbon atom.
