CuCOOH

CuCOOH is not a widely recognized or isolable chemical compound in standard inorganic chemistry. The notation can appear in discussions of copper carboxylate chemistry or as a simplified way to refer to a copper–carboxylate fragment, but there is no well-characterized discrete molecule with the exact formula CuCOOH under normal conditions. In practice, copper forms stable carboxylates of the type Cu(O2CR)2 or related polymeric networks, where carboxylate groups bridge copper centers.

Structure and nomenclature are therefore generally described in terms of copper(II) carboxylates or copper(I) carboxylate complexes rather than a single molecular species CuCOOH. In solid-state forms, these compounds often exist as polymeric or network structures in which copper centers are coordinated by carboxylate ligands, sometimes with additional ligands such as water or amines. A monomeric CuCOOH as a neutral unit is not generally reported as a isolable compound.

Preparation and occurrence are typically discussed in the context of copper salts reacting with carboxylate sources, such as formate or acetate, yielding copper carboxylates or coordination polymers. These materials have been explored in coordination chemistry, catalysis, and materials science, including as precursors to copper-containing catalysts or as components in metal–organic frameworks.

Safety and handling follow general precautions for copper compounds. They can be irritants and may pose risks if ingested or inhaled in powder form. Proper laboratory practices, including use of gloves and eye protection, should be observed.
