peroksiidides

Peroksiidides are a class of chemical compounds characterized by the presence of a peroxy linkage, specifically the group –O–O–, where an oxygen atom is bonded to another oxygen atom. These compounds are distinct from peroxides, which typically contain the –O–O– group bonded to other elements or groups. Peroksiidides are less common and often found in coordination chemistry, where they act as ligands in metal complexes.

The term "peroksiidide" is derived from the combination of "peroxy" (referring to the –O–O– group) and "anion," as these compounds often exhibit anionic properties. They are typically formed through the reaction of metal ions with hydrogen peroxide or other peroxy sources under basic conditions. The resulting complexes often feature metal-oxygen bonds where the oxygen is part of a peroxy bridge, stabilizing the coordination environment around the metal center.

Peroksiidides are notable for their role in catalysis, particularly in oxidation reactions, where they facilitate the transfer of oxygen atoms to substrates. They are also studied for their potential applications in materials science, such as in the development of magnetic or conductive materials. Some peroksiidides exhibit unusual structural properties, including unusual coordination geometries or magnetic behaviors, making them subjects of interest in inorganic chemistry.

Despite their potential utility, peroksiidides are relatively unstable compared to other coordination compounds, often decomposing upon heating or exposure to light. Their synthesis requires careful control of reaction conditions to prevent decomposition or the formation of unwanted byproducts. Research into peroksiidides continues to explore their reactivity, stability, and potential practical applications in various chemical and industrial processes.
