  摘要：

  镧系元素（III）与分子式为Ln（btc）·nH 2 O的偏苯三酸（1,2,3-苯三甲酸，H 3 btc）的配合物，其中 Ln =镧系元素（III）离子， n = 2-6制备并通过元素分析，红外光谱，X射线衍射图和热分析进行表征。配合物的红外光谱表明镧系元素（III）在所有羧酸根基团上的配位。La（III），Ce（III），Pr（III）和Er（III）的络合物是无定形的。在空气中加热时，所有配合物都会损失水分子，接下来的无水化合物会分解为相应的金属氧化物。

  The present invention relates to curatives for epoxy resins, and compositions (e.g. adhesives) containing such resins cured using the same methods of preparation and uses therefor. More specifically, the present invention relates to hybrid curatives for epoxy resins comprising both aromatic amine, phenol and/or phenyl ester moieties. A further aspect of the current invention relates to new imidazole catalysts that possess a combination of excellent cure latency as well as low cure temperature onset.

  Nine new coordination polymers: [Cu3(ipO)2(pyz)2] (5), [Cu3(ipO)2(4-phpy)(H2O)2] (6), [Cu(ip)(4-phpy)2] (7), [Cu3(ipO)2(H2O)2] (8), [Co(phen)(ip)(H2O)] (9), [Co3(1,2,3-btc)2(4,4′-bpy)2(H2O)2]·2H2O (10), [Ni(1,2,3-btcH)(4,4′-bpy)(H2O)]·H2O (11), [Cd5(1,2,3-btc)2(1,2,3-btcH)2(4,4′-bpy)3(H2O)2] (12) and (1,2,3-btcH3)(4,4′-bpy) (13) (1,2,3-btcH3 = 1,2,3-benzenetricarboxylic acid, ipO = 2-hydroxyisophthalate, 4,4′-bpy = 4,4′-bipyridine, pyz = pyrazine, 4-phpy = 4-phenyl-pyridine and phen = o-phenanthroline) have been hydrothermally synthesized. This family of compounds show the role of the N-containing heterocyclic ligands and Cu(II) ions in the metal–ligand reactions. These results suggest that the hydroxylation requires Cu(II) ions as the oxidant, rather than the presence of N-containing heterocyclic ligands, while the decarboxylate procedure requires high temperature and basic condition rather than the participation of Cu(II) ions. The obtained compounds show versatile structures and magnetic properties due to the flexibility of the carboxylate ligands. Compound 5 shows dominated antiferromagnetic interaction in the [Cu2(μ-ipO)2] unit, and no long-range magnetic ordering behaviour. Compound 10 has a topologically ferrimagnetic chain with alternating CoIIoctCoIItetCoIIoct (oct = octahedral, tet = tetrahedal) spin arrangement. The CoIItet and CoIIoct ions are bridged by similar syn–anti carboxylates (CoIItet⋯CoIIoct 4.616 and 4.735 Å). Such a chain shows ferro- and antiferro- magnetic interactions and no long-range magnetic ordering behaviour was observed. Compound 11 has a antiferromagnetic coupled syn–anticarbxylate-bridged Ni(II) chain (J = 1.48(2) K), and shows long-range magnetic order below 2.6 K due to the extensive hydrogen bonds between the chains.

  九种新的配位聚合物：[Cu3(ipO)2(pyz)2] (5)、[Cu3(ipO)2(4-phpy)(H2O)2] (6)、[Cu(ip)(4-phpy) 2] (7), [Cu3(ipO)2(H2O)2] (8), [Co(phen)(ip)(H2O)] (9), [Co3(1,2,3-btc)2( 4,4‐bpy)2(H2O)2]·2H2O (10), [Ni(1,2,3-btcH)(4,4‐bpy)(H2O)]·H2O (11 ), [Cd5(1,2,3-btc)2(1,2,3-btcH)2(4,4‐bpy)3(H2O)2] (12) 和 (1,2,3- btcH3)(4,4–bpy) (13) (1,2,3-btcH3 = 1,2,3-苯三甲酸，ipO = 2-羟基间苯二甲酸酯，4,4–bpy = 4,4– 2-联吡啶、pyz = 吡嗪、4-phpy = 4-苯基吡啶和 phen = 邻菲咯啉）已通过水热合成。该族化合物显示了含氮杂环配体和 Cu(II) 离子在金属配体反应中的作用。这些结果表明，羟基化需要Cu(II)离子作为氧化剂，而不是含氮杂环配体的存在，而脱羧过程需要高温和碱性条件，而不是Cu(II)离子的参与。由于羧酸配体的灵活性，所获得的化合物显示出多种结构和磁性。化合物 5 在 [Cu2(μ-ipO)2] 单元中显示出主导的反铁磁相互作用，并且没有长程磁有序行为。化合物 10 具有拓扑亚铁磁链，具有交替的 CoIIoctCoIItetCoIIoct（oct = 八面体，tet = 四面体）自旋排列。 CoIItet 和 CoIIoct 离子通过类似的顺反羧酸盐桥接（CoIItet→CoIIoct 4.616 和 4.735 →）。这样的链显示出铁磁和反铁磁相互作用，并且没有观察到长程磁有序行为。化合物 11 具有反铁磁耦合顺反羧酸桥 Ni(II) 链 (J = 1.48(2) K)，并且由于链之间广泛的氢键而显示出低于 2.6 K 的长程磁序。

  The invention provides epoxy and oxetane compositions including the novel acyloxy and N-acyl curing agents described herein. Use of invention curing agents result in cured adhesive compositions with remarkably increased adhesion and reduced hydrophilicity when compared to resins cured with other types of curing agents. Furthermore, the curatives of this invention do not interfere with free-radical cure and are thus suited for use in hybrid cure thermoset compositions.
