Mix and match: The first structural examples of M-M multiple bonds between different first-row transition metals are elucidated using X-ray crystallography (see picture; Fe pink, Cr green, P yellow, N blue), spectroscopic methods, and calculations. The Fe-Cr bonds are ultrashort (<2 Å) with highly delocalized σ and π bonds and unusually large quadrupole splittings in Mössbauer spectroscopy.
