1D nickel(II) coordination polymer with pyrimidine and pivalate bridges: Synthesis, structure and magnetic properties

New 1D polymeric compound [Ni-2(mu-OH2)(mu-Piv)(2)(Piv)(2)(mu-pym)(eta(1)-pym)(2)](n) (3, Piv is an anion of pivalic acid) was synthesized upon the reaction of the nickel(II) pivalate complex Ni-9(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 anti-ferromagnetic interactions with two exchange parameters of J(1) = -3.1 and J(2) = -1.2 cm(-1).
