Abstract: The title compound, {(C₆H₁₆NO)[Cu₂(CH₃COO)₅]·CH₂Cl₂}_n, consists of acetate-bridged Cu₂(CH₃COO)₄ units that are connected via another acetate anion at each terminus to form infinite anionic [{Cu₂(CH₃COO)₄}(CH₃COO)]_n chains along [100]. The connecting acetate is hydrogen bonded to the diethyl(2-hydroxyethyl)ammonium cation, and the dichloromethane solvent molecule fills the remaining voids in the structure. The O-Cu-Cu angles along the polymeric chain are nearly linear [175.49 (5)°], but individual O-Cu-Cu-O units along the chain are bent and rotated against each other at the bridging acetate ion. Translation of each Cu₂(CH₃COO)₄ unit along the chain, represented by the least-squares plane of the two copper ions along with four of the acetate O atoms, rotated these units by 35.16 (3)°.
