  Ferromagnetic interactions mediated by syn–anti carboxylate bridging in tetranuclear copper(II) compounds

  摘要：

  The tridentate ligand N-(2-hydroxypropyl)aminopropionic acid (H(2)hap) and the tripod ligand nitrilodi(propionic acid) acetic acid (H(3)ndpa) have been synthesised and found to interact with Cu(II) to produce tetranuclear compounds. In the cyclic complex [Cu(Hhap)(NO3)](4) (1), the four Cu(II) centres form a slightly buckled square linked via syn-anti carboxylate bridges. In [Cu-4(ndpa)(2)(H2O)(8)(NO3)(2)].2H(2)O (2), and [Cu-4(ndpa)(2)(H2O)(10)]SO4.6H(2)O (3), two Cu(II) centres are each chelated by a ndpa(3-) ligand which in turn are linked by coordination of the outer carboxylate oxygens on the longer propionate arms of the ligands to two further {Cu(H2O)(3)}(2+) units resulting in a rhomboid array of Cu(II) centres. In the closely related complexes [Cu-4(ndpa)(2)(H2O)(6)Cl-2].4H(2)O (4), and [Cu-4(ndpa)(2)(H2O)(6)Br-2].4H(2)O (5), replacement of one aqua ligand by an outer carboxylate oxygen from the shorter acetate arm of an adjacent complex results in the formation of infinite sheets of linked tetranuclear units. Magnetic studies performed between 1.8 and 300 K on these complexes indicate that ferromagnetic or antiferromagnetic coupling between Cu(II) ions can be observed depending on the geometry of the carboxylate bridging mode. Compound 1 shows a paramagnetic behaviour with a ferromagnetic interaction (J/k(B) = + 3.9 K, S = 2 ground state) between adjacent Cu(II) ions through equatorial-equatorial syn-anti carboxylate bridges. In compound 2, within the rhombus motif ferromagnetic (J(1)/k(B) = + 12.1 K) and antiferromagnetic (J(2)/k(B) = -0.4 K) interactions through syn-anti bridges but in equatorial-equatorial and equatorial-axial modes, respectively, are present. Finally, in the 2-D 4 and 5 the linkage of the rhombus motif, which is isolated in 2, by equatorial-axial anti-anti carboxylate bridges, leads to dominating ferromagnetic interactions (J' = +0.2 K) between the ferromagnetically interacting Cu(II) dimers (J(1) = +8.8 K).

  一种无氯离子绿色螯合剂的合成方法

  摘要：

  本发明公开了一种无氯离子绿色螯合剂的合成方法，合成方法具有两个步骤：步骤一，将氨基酸溶于甲醇或乙醇，再加入氢氧化钾反应，反应完成后，加入丙烯酸酯，反应完成后得到粘状液体；步骤二，将粘状液体加入硫酸溶液，进行水解反应，制得的晶体即为螯合剂。本发明将氨基酸在碱的作用下使氨基酸产生氨基，氨基与丙烯酸酯发生迈克尔加成，再将得到的产物进行水解从而得到相应的绿色的氨基酸衍生螯合剂，合成过程简单，不需要复杂的工艺及设备，使得生产成本能够大大降低。

  In a polyester production method, a titanium compound having a radical selected from a carbonyl group, a carboxyl group, or an ester group, and a phosphorous compound having a structure illustrated in Formula (I), are added. 1 This yields a polyester composition which does not exhibit increased filter pressure when forming, which has excellent filament and film forming properties, and which has a polymer color tone superb to that of conventional products.
