Herein, we report a distinct Cr-Cr sextuple bond with an ultra-short length stabilized by equatorial alkali metals. Bonding analyses indicate that the two desired 4p-pi bonds failed to be formed but the bonding strength is enhanced due to the introduction of alkali metals, weakening the Cr-Cr 4s-4s effect. The Cr-Cr sextuple bond comprises five explicit 3d-3d overlaps and another delocalized σ bond.
