catena-Polytriethyl­ammonium tetra-μ-acetato-κ8O:O′-dicuprate(II)-μ-acetato-κ2O:O′ tetra­hydro­furan monosolvate

摘要

In the title compound, {[(C2H5)3NH][Cu2(CH3COO)5]·C4H8O}n, the two different Cu^II atoms are coordinated in a pseudo-square-pyramidal environment by five O atoms from the acetate ligands. Neighbouring pairs of Cu^II atoms are linked by four basally coordinating bridging acetate ligands as in the crystal structure of copper acetate monohydrate. The fifth, apically coordinating ligand links two of the dicopper tetra­acetate paddlewheel-units together, thus building a linear coordination polymer which extends along [10-1]. Each apical acetate ligand is linked by an N—H⋯O hydrogen bond to a triethyl­ammonium cation. Weak C—H⋯O hydrogen bonding interactions also occur.
