Abstract

In this study, we synthesized two hybrid compounds based on Anderson [C₁₆H₃₄N₂Mo₆AlNaO₂₈] (AL) and Keggin [C₃₂H₄₈N₄Mo₁₂SiO₄₄] (KL) polyoxometalate (POM) and characterized their structures by various spectroscopic methods. In order to decorate Anderson and Keggin POM compounds, 4-pyridinepropanol (4-PyP-OH) compound was used and the organic–inorganic hybrids were prepared. The single crystals of the organic–inorganic hybrids AL and KL were obtained from aqueous solution and their molecular structures were solved by X-ray crystallography method. DNA binding properties of the hybrids AL, KL, POMs and 4-PyP-OH were investigated by the electronic spectroscopy and viscosity measurements. The emission and excitation properties of the compounds were investigated by the photoluminescence method. The redox properties of the compounds were investigated by cyclic voltammetry method in the −1.0 – 1.5 V range and it was determined that they generally exhibit irreversible redox events in this potential range. Thermal behaviours of the hybrids AL and KL in the 20–750 °C temperature range were investigated by the thermal methods.

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
