本文报道了酰基吡唑啉酮盐及其主族元素、过渡金属、稀土元素和吖系元素的配合物的合成，并用单晶X射线结晶学、核磁共振和红外光谱等手段进行了表征。这些配合物由两个、三个或四个与金属原子结合的酰基吡唑酮配体组成，形成了一组结构不同的具有(扭曲的)八面体、五角形-双锥体或反棱柱排列的配位配合物。一些配合物在固体状态下被证明是聚合物，包括非双金属钠/稀土配位聚合物。通过TG/DTA测试分析了一系列聚合物，以确定其稳定性。反过来，这些配体又很容易从商业上可以买到的盐酸肼盐中以良好的产率合成。这些发现表明，酰基吡唑啉酮配体可以与不同离子半径的金属形成络合物，特别是它们在其他领域的应用，如分析和金属有机框架化学。介绍了具有代表性的主族、过渡金属、镧系元素和吖系吡唑酮类化合物的合成和结构分析。
The synthesis of acylpyrazolone salts and their complexes of main group elements, transition metals, lanthanides, and actinides are described and characterized inter alia by means of single-crystal X-ray crystallography, NMR, and IR spectroscopies. The complexes consist of two, three, or four acylprazolone ligands bound to the metal atom, resulting in a structurally diverse set of coordination complexes with (distorted) octahedral, pentagonal-bipyramidal, or antiprismatic arrangements. Several complexes proved to be polymeric in the solid state including heterobimetallic sodium/lanthanide coordination polymers. A selection of the polymeric compounds was analyzed via TG/DTA measurements to establish their stability. The ligands, in turn, were readily synthesized in good yields from commercially available hydrazine hydrochloride salts. These findings demonstrate that acylpyrazolone ligands can form complexes with metals of varying ionic radii, highlighted by their utility in other areas such as analytical and metal organic framework chemistry. The syntheses and structural analyses of the representative main group, transition metal, lanthanide, and actinide pyrazolonato complexes highlighted in red are presented.
