Single\u2010crystal X\u2010ray diffractometry (SC\u2010XRD) analysis revealed that it has a short Cr\u2212N bond distance of 1.8878(9)\u2005\u00c5, which could be attributed to the relatively less bulky nature of the amido ligand compared with reported systems. Furthermore, the oxidation reaction of the two\u2010coordinate Cr(II) complex was explored.
