Abstract
In order to understand the trends of the M4 skeleton to deform in planar clusters of type M4(CO)16, extended Hückel calculations have been performed. Depending on the total electron count the shape transforms ideally from square to rhombus through the formation of one diagonal M-M bond (64 → 62e-). The nature of the annular and transannular M-M σ-interactions is illustrated.File in questo prodotto:
