Catena-Poly[dieth-yl(2-hydroxy-ethyl)-ammonium [[tetra - μ- acetato-κ8 O:O′-dicuprate(II)(Cu - Cu)] - μ- ao-2 O:Oκ] dic′hloro-methane solvate]

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 dieth-yl(2-hydroxy-ethyl)ammonium cation, and the dichloro-methane solvent mol-ecule 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)°.
