  Versatile coordination mode of dicyanamide in nickel(II) complexes containing polyamines as blocking ligands

  摘要：

  Triethylenetetramine (L-4) and dipropylenetriamine (L-3) were used as blocking ligands (tetradentate and tridentate, respectively) that, after complexation with Ni(II), leave two or three sites ready for ligation with N(CN)(2)(-) (dicyanamide, abbr. dca). The formed complexes are mononuclear, binuclear or polymeric. This was proven by the X-ray structure analysis for [NiL4(dca)(2)] (mononuclear, 1), [(dca)(LNi)-Ni-3(dca)(2)NiL3(dca)] (binuclear, 2) and [NiL4(dca)](ClO4) (polymeric, 3). The magnetic susceptibility measurements for 1 confirm that the Curie law is obeyed at higher temperatures whereas the zero-field splitting is effective below 10 K (D/hc = -4 cm(-1)); 2 shows a weak anti ferromagnetic coupling (J/hc = -0.6 cm(-1)); 3 exhibits a negligible exchange coupling (J/hc approximate to 0).

  The first structural determination of dinuclear compounds with μ1,5-dicyanamide [dca, N(CN)2−] as bridging ligand has been achieved with the products of formula [Ni(µ1,5-dca)(dca)(dpt)]2 (1) and [Ni(µ1,5-dca)(dca)(medpt)]2 (2) [dpt = bis(3-aminopropyl)amine and medpt = bis(3-aminopropyl)methylamine]. The X-ray diffraction analysis reveals dinuclear compounds with double μ1,5-dicyanamide bridges. The

  使用式 [Ni(μ1,5-dca)(dca)(dpt)] 的产物实现了以 μ1,5-双氰胺 [dca, N(CN)2−] 作为桥连配体的双核化合物的首次结构测定2 (1) 和 [Ni(μ1,5-dca)(dca)(medpt)]2 (2) [dpt = 双（3-氨基丙基）胺和 medpt = 双（3-氨基丙基）甲胺]。X 射线衍射分析显示具有双 μ1,5-双氰胺桥的双核化合物。镍原子是六配位的。末端配体（dpt 或 medpt）的微小差异导致磁行为发生剧烈变化：1 的磁化率测量显示弱反铁磁耦合（J = -1.2 cm-1，g = 2.29），而 2 显示铁磁耦合（J = 0.7 cm−1，g = 2.17）。还描述了相关化合物 (μ-对苯二甲酸)[Ni(dca)(dpt)(H2O)]2 (3)。X 射线衍射分析揭示了具有末端 dca 配体的双核对苯二甲酸酯桥连 NiIII 化合物。3 的磁化率测量表明弱反铁磁耦合：J
