Structure of <a href="https://en.wikipedia.org/wiki/dicobalt_octacarbony" class="extiw" title="en:dicobalt octacarbony">dicobalt octacarbony</a>. Spectroscopic and other structural studies indicate that this chemical may exist as a rapidly interconverting mixture of isomers. One of the minor isomers is displayed here, containing direct bond between the two Co atoms, each of which has <a href="https://en.wikipedia.org/wiki/Trigonal_bipyramidal_molecular_geometry" class="extiw" title="en:Trigonal bipyramidal molecular geometry">trigonal–bipyramidal geometry</a> on cobalt (bound on their equatorial positions), with a structure of (CO)<sub>4</sub>Co–Co(CO)<sub>4</sub> and having D<sub>2d</sub><a href="https://en.wikipedia.org/wiki/symmetry_group" class="extiw" title="en:symmetry group">molecular symmetry</a>.
