• Here are the synthesis, structure and magnetic properties of 36-nuclear complexes of nickel(II) and cobalt(II) with anions of dimethylmalonic acid. [Display omitted] The reaction of (NBu4)2Me2Mal (where Me2Mal2− is dimethylmalonate dianion) with cobalt(II) or nickel(II) acetates M(OAc)2·4H2O (M=CoII or NiII) gave (NBu4)6[Co36(H2O-κO)12(μ3-OH)20(μ4-HMe2Mal-κ2O,O′)2(μ4-Me2Mal-κ2O,O′)22(μ4-Me2Mal)6]·3EtOH (1) and (NBu4)8[Ni36(H2O-κO)12(μ3-OH)20(μ4-Me2Mal-κ2O,O′)24(μ4-Me2Mal)6]·6H2O·2EtOH (2), respectively. Replacement of the aqueous NBu4OH solution by a methanolic solution allowed us to isolate the 36-nuclear complex (NBu4)8[Co36(H2O-κO)12(μ3-OH)20(μ4-Me2Mal-κ2O,O′)24(μ4-Me2Mal)6]·2.5H2O·CH3OH (3). Complexes 1–3 were characterized by IR spectroscopy, single crystal X-ray diffraction analysis, and magnetochemical studies.
