Investigations into the anion effects on the molecular construction of a series of CuX2 (X− = BF4−, ClO4−, and NO3−) complexes with 1,3,5-tris(isonicotinoyloxyethyl)cyanurate (L) were carried out. Suitable combinations of tridentate N-donor ligands and a variety of coordination geometries of copper(II) ions produce unique 1D, 2D, and 3D coordination polymers containing open cavities suitable for small chemical species, according to the nature of the polyatomic anions. Indeed, the anion exchangeability and catalytic effects of these polymers are strongly dependent on subtle anion differences, including solubility. Calcination of [Cu(ClO4)(L)(Me2SO)2](ClO4)·2CH2Cl2 crystals preserves its crystallinity at 200 °C, and at 600 °C finally produces stick-shaped microcrystalline copper(II) oxide.
研究了阴离子对一系列 CuX2(X− = BF4−、ClO4− 和 NO3−)与 1,3,5-三(异烟酰氧基乙基)氰尿酸酯(L)配合物分子结构的影响。根据多原子阴离子的性质,三齿N-供体配体和铜(II)离子的各种配位几何形状的合适组合产生独特的1D、2D和3D配位聚合物,其中含有适合小化学物质的开放空腔。事实上,这些聚合物的阴离子交换性和催化作用强烈依赖于细微的阴离子差异,包括溶解度。 [Cu(ClO4)(L)(Me2SO)2](ClO4)·2CH2Cl2晶体在200℃下煅烧仍保持其结晶度,在600℃下最终生成棒状微晶氧化铜(II)。
