Closer than most: A series of four dichromium bis(amidinate) complexes of the type [Cr2{μ-η2-ArNC(R)NAr}2] display an extremely short metal–metal bond of 1.74 Å, independent of the steric hindrance of the ligands. DFT calculations of Cr[BOND]Cr bond lengths agree well with the experimental values and computational analysis of their electronic structures indicates quintuple bonding between the two Cr centers.
