Mononuclear pivalates of metals of the first transition series

详细

The synthesis and structures of mononuclear Ni(II), Co(II), Mn(II), and Cu(II) pivalates isolated as complex salts NBu₄[M(Piv)₃] ((NBu₄)⁺ is tetrabutylammonium cation, Piv^– is pivalate anion) and polynuclear complexes [Ni₆(L)₂(HL)₂(Piv)₆(HPiv)₈], (NBu₄)₂[Co₄(Piv)₈(AcO)₂(H₂O)₄], NBu₄[Co₂(Piv)₅(H₂O)₂], and (NBu₄)₂[Cu₄(Piv)₈(AcO)₂(H₂O)₂] (L^2–, HL^–, and AcO^– is lactic acid dianion, lactic acid monoanion, and acetate anion, respectively) are discussed. The formation of the compounds is detected during the development of the synthesis of NBu₄[M(Piv)₃].
