The present work describes the complexation properties of two oxime-containing Schiff bases (used as ligands), viz. 2-hydroxyimino-N'-[1-(2-pyridyl)ethylidene]propanohydrazone (Hpop) and 2-hydroxyimino-N'-[(pyridine-2-yl)methylidene]propanohydrazone (Hpoa), with Co(II) ions in DMSO/water solution. Volumetric (oxygenation) studies were carried out to determine the uptake of molecular oxygen O in the formation of the complexes Co(II)-Hpop and Co(II)-Hpoa. The acquired data can be useful in the development of oxygen bioinorganic complexes of metal ions with Schiff base ligands in solution. Their properties allow them to be used as synthetic oxygen transporters. Moreover, the binding of dioxygen could play an important role in the research of catalytic activity by such systems.
本工作描述了两种含肟的希夫碱（用作配体），即 2-羟亚氨基-N'-[1-(2-吡啶基)亚乙基]丙二酰肼（Hpop）和 2-羟亚氨基-N'-[(吡啶-2-基)亚甲基]丙二酰肼（Hpoa）与 Co(II)离子在 DMSO/水溶液中的络合性质。进行了容量（氧合）研究，以确定在形成配合物 Co(II)-Hpop 和 Co(II)-Hpoa 时对分子氧 O 的吸收。获得的数据可用于开发金属离子与希夫碱配体在溶液中形成的氧生物无机配合物。它们的性质允许它们被用作合成氧载体。此外，氧的结合在这类体系的催化活性研究中可能起着重要作用。
