(60) Crystal structures of four diene–cobalt complexes were examined in order to determine the mode of bonding. It was noted that the substituents on the C-1 and C-4 were displaced considerably out of the plane of the diene, an indication of possible rehybridization of those carbons upon ...
Cobalt (Co, atomic number 27, in group 9 of the periodic table of the elements, atomic mass 58.9, density 8.9 g/cm3) is a shiny gray, hard, ductile, and brittle metal with magnetic properties. Cobalt prefer oxidation states (II) or (III), the former is most stable. Cobalt carbonyl ...
