Abstract

The crystal structure of [Cu~2~(cit)(phen)~2~]·6H~2~O (1) (citcitrate anion, phen1,10‐phenanthroline) reveals an unusual hydrogen‐bonded water dodecamer. The centrosymmetric dodecamer contains a decameric core with two pensile monomers, which is described as a chair with two handles. The structure, being predicted to be relative stable to other dodecameric structures, is stabilized by hydrogen bonding with the carboxylate groups of citrate ligands. The variable‐temperature magnetic study of 1 shows weak antiferromagnetic interaction.
