By treating diphosphinito[PCP]-pincer ligand,(Ph2P(ortho-C6H4))2CH2(1) with CoMe(PMe3)4 or CoMe3(PMe3)3 the same Csp3-H bond activation product[PCP]Co(I)(PMe3)(2) was obtained at room temperature. Treatment of 2 with C6Cl6, EtBr or n-BuBr and CH3I gave rise to the single electron oxidation addition products[PCP]Co(II)X(PMe3)[X=Cl(3), Br(4) and I(5)]. The molecular structures of 2~6 were confirmed by X-ray diffraction analysis.

Key words: Csp3-H activation, pincer complex, cobalt complex
