Shorter than ever : Reduction of chromium(II/III) chlorides stabilized by amidopyridinato ligands leads to a dichromium complex that has a Cr–Cr bond length of 1.75 Å. This bond is exceptionally short, even for bonding orders higher than four, and is at present the shortest reported metal–metal bond for a stable compound. The experimental results are supported by theoretical calculations.
