Cd2Ionen

Cd2Ionen refers to the chemical species containing cadmium in a +2 oxidation state and two iodide anions. This combination typically forms cadmium iodide, a salt with the chemical formula CdI2. Cadmium iodide is an inorganic compound that appears as a white crystalline solid. It is soluble in water, and also in many organic solvents like ethanol and acetone. Cadmium iodide is known for its layered crystal structure, similar to that of cadmium chloride, where cadmium atoms are octahedrally coordinated by iodide ions. This structure contributes to its properties, including its relatively low melting point for an ionic compound. Cadmium iodide has found various applications. Historically, it was used in photography, particularly in developing photographic plates due to its photosensitive properties. More recently, it has been investigated for use in thin-film transistors and as a component in certain types of solar cells. However, it is important to note that cadmium compounds, including cadmium iodide, are considered toxic and require careful handling and disposal.
