The reaction of (ArL)Co(py) with tBuN3 afforded the isolable three-coordinate Co-imido complex (ArL) Co(NtBu), which is paramagnetic at room temperature. Variable-temperature (VT) 1H NMR spectroscopy, VT crystallography, and magnetic susceptibility measurements revealed that (ArL)Co(N tBu) undergoes a thermally induced spin crossover from an S = 0 ground state to a quintet (S = 2) state. The reaction of (ArL)Co(py) with mesityl azide yielded an isolable S = 1 terminal imido complex that was converted into the metallacycloindoline (ArL)Co(κ2- NHC6H2-2,4-Me2-6-CH2) via benzylic C-H activation.
