N2 - The title complex, [Cu-4(C2H3O2)(6)(OH)(2)(C5H11N)(4)]center dot 2H(2)O, possesses an unusual inversion-symmetric tetranuclear copper framework, with each CuII atom displaying a square-pyramidal geometry and one additional long Cu...O contact. The four piperidine ligands are terminal, one at each CuII atom, and the two hydroxide ligands are triply bridging. The six acetate ligands exhibit two distinct coordination modes, namely as two monodentate acetates and four bridging acetates that bridge the two inequivalent copper centres. The noncoordinating acetate O atom is involved in intramolecular hydrogen bonding with H atoms from the hydroxide and one piperidine ligand. In addition, extensive intermolecular hydrogen bonding involving the solvent water molecules is observed.
