Under pressure : characterization of the high‐pressure phase of crystalline [Co 2 (CO) 6 (PPh 3 ) 2 ] has provided the first structural evidence for the transformation from a staggered to eclipsed arrangement of the equatorial carbonyl ligands in a dimeric transition‐metal complex (see picture). A comparison with the same phenomenon observed at low temperature (though arrested in the very early stages) is presented.
