Abstract

In the title compound, [CuNa3(CH3CO2)5(CH3COOH)(H2O)2]n, the CuII atom lies on an inversion center and is coordinated by four O atoms from four acetate ligands, leading to a square-planar geometry. One NaI atom, lying on an inversion center, is coordinated by four O atoms from four acetate ligands and two bridging water molecules in a distorted octahedral geometry. The other NaI atom is coordinated by five O atoms from five acetate ligands and a bridging water molecule. A hydroxy H atom lies on a twofold rotation axis and is shared by two acetate ligands. The crystal packing exhibits a polymeric layer parallel to (100), which is further stablized by intralayer O—H⋯O hydrogen bonds. The layers are linked by interlayer O—H⋯O hydrogen bonds.
