合成了一种新的三噻吩类配体（L=3-（2-吡啶基）-5-（2，2 ′：5′，2 ″-三噻吩-3 ′-基）吡唑）。Ni（BF 4）2·6 H2O，L和nBu 4 N [Fe（CN）3 tp]（tp =三（3，5-二甲基吡唑-1-基）硼氢化物）与NaBPh 4在甲醇/丙酮中反应，得到一个氰根桥联的四核配合物[Fe 2Ni 2（CN）6（tp）2（L）4]（BPh 4）2（1）。研究了1和L的电化学性质，并对1进行了磁化率测量，揭示了铁磁相互作用在四核核心内起作用。
A new terthiophene based ligand (L=3-(2-pryridyl)-5-(2,2′:5′,2″-terthien-3′-yl) pyrazole was synthesized. The reaction of Ni(BF4)2·6H2O, L and nBu4N[Fe(CN)3tp∗] (tp∗=tris(3,5-dimethylpyrazol-1-yl)borohyrdide) with NaBPh4in MeOH/acetone yielded a cyanide bridged tetranuclear complex [Fe2Ni2(CN)6(tp∗)2(L)4](BPh4)2(1). The electrochemical properties of both 1 and L were investigated, and magnetic susceptibility measurements of 1 were conducted, revealing that ferromagnetic interactions were operative within the tetranuclear core.
