文摘
New 1D polymeric compound [Ni2(μ-OH2)(μ-Piv)2(Piv)2(μ-pym)(η1-pym)2]n (3, Piv is an anion of pivalic acid) was synthesized upon the reaction of the nickel(II) pivalate complex Ni9(OH)6(Piv)12(HPiv)4 (3) and pyrimidine (pym) in MeCN. Complex 3 was characterized by the X-ray diffraction study and magnetic measurements. It is shown that neighboring Ni sites in the 1D metal chain in 3 are coupled by weak antiferromagnetic interactions with two exchange parameters of J1 = –3.1 and J2 = –1.2 cm–1.
