[Ag(CF3SO3)(L1)(H2O)0.5]2·2CH2Cl2·H2O (3). The molecular square units comprise two metal ions bridged by two ligands. Isomorphic complexes 1 and 2 accommodate two toluene molecules above and below the molecular square. L1 reacted with Cu(hfac)2 and CuI to yield zigzag, [Cu(hfac)2(L1)]}n·0.25n(CH2Cl2) (4), and ribbon-shaped, [Cu4I4(L1)2]}n (5), coordination polymers. In 4, L1 behaves as a bidentate N,N-ligand bridging
多种金属配体和无机-有机杂化桥联配体已被掺入多核络合物和双金属配位聚合物中。二茂铁表现出氧化还原活性和易于化学修饰,是一种多用途的金属配体组分。然而,大多数具有含二茂铁的配体的金属络合物形成离散的低维螯合物或配位聚合物。因此,我们设计并合成了基于二茂铁的多齿配体1,2,2-二(4-吡啶硫基)二茂铁(L1)和1,2-二(2-吡啶硫基)二茂铁(L2)。在这里,我们报告的合成和分子方形络合物和配位聚合物包含的结构L1,它与M(HFAC)反应2(hfac = 1,1,1,5,5,5-六氟乙酰丙酮酸酯)和AgCF 3 SO 3产生分子方形配合物[M(hfac)2(L1)] 2 ·2C 6 H 5 CH 3 [M = Ni(1)和Co(2)]和[Ag(CF 3 SO 3)(L1)(H 2 O)0.5 ] 2 ·2CH 2 Cl 2 ·H 2 O(3)。分子正方形单元包含由两个配体桥接的两个金属离子。同
