This talk will discuss computational and experimental results on M2(allyl)4 and M2(acetate)4 complexes (M = Cr, Mo, W, Re) of interest to the Al's in my career (Cotton & Sattelberger). Cr & Mo tetraallyls have bridged bimetallic structures, while the Re complex has all terminal allyls. Computational comparisons between "ancient" SCF-Xα-SW and modern DFT calculations on these systems will be presented and the structural differences explained. Computational results on the M2(acetate)4 systems will be discussed to clearly illustrate why "heavier is better".

Heavier the better: Something old, something new, nothing radioactive
