CuCH3COO2H2O

CuCH₃COO·2H₂O, commonly known as copper(II) acetate monohydrate, is an inorganic coordination compound composed of copper, acetate ions, and water molecules. It is a blue crystalline solid that belongs to the class of copper(II) salts, characterized by its coordination chemistry and hydrated structure.

The compound features a central copper(II) ion coordinated by four acetate ligands and two water molecules. The acetate ions (CH₃COO⁻) act as bidentate ligands, forming a square planar or distorted octahedral geometry around the copper center. The presence of two water molecules further stabilizes the structure, contributing to its hydrated nature.

Copper(II) acetate monohydrate is typically prepared through the reaction of copper(II) oxide or copper(II) hydroxide with acetic acid, followed by crystallization. It is soluble in water and polar solvents but exhibits limited solubility in nonpolar organic solvents. The compound is often used as a precursor in organic synthesis, particularly in the preparation of other copper-based catalysts or reagents.

In addition to its synthetic applications, CuCH₃COO·2H₂O has been studied for its catalytic properties in various reactions, including cross-coupling processes and oxidation reactions. Its blue color and coordination environment make it useful in materials science for applications such as pigments or as a component in hybrid organic-inorganic frameworks.

The compound is relatively stable under normal conditions but can decompose upon heating, releasing acetic acid and water. It should be handled with care, as copper(II) compounds can exhibit mild toxicity and may cause skin or eye irritation. Proper storage in a cool, dry environment is recommended to prevent decomposition or contamination.
