Tetracyanoethylene oxide (TCNEO) reacted with [CpCo(dithiolene)] (Cp = η5-cyclopentadienyl) complexes having 4-pyridyl or 3-pyridyl group to undergo a dicyanomethylation to the nitrogen atom on the pyridyl group. The reaction of [CpCo(S2C2(4Py)2)] (1) with TCNEO formed both the monodicyanomethylated [CpCo(S2C2(4Py)(4Py–C(CN)2))] (1a) and bisdicyanomethylated [CpCo(S2C2(4Py–C(CN)2)2)] (1b). [CpCo(S2C2(2Py)(4Py))]
