title: Poly[[diaquatris(mu6-benzene-1,2,4,5-tetracarboxylato)tris(mu2-4,4'-bipyridine)hexacopper(II)] dihydrate].
abstract: The hydrothermal reaction of an aqueous solution of Cu(CH(3)COO)(2).H(2)O, 1,2,4,5-benzenetetracarboxylic acid and 4,4'-bipyridine gave rise to the interesting title three-dimensional polymer [[Cu(6)(btec)(3)(4,4'-bpy)(3)(H(2)O)(2)].2H(2)O](n) (btec is 1,2,4,5-benzenetetracarboxylate, C(10)H(2)O(8)(4-), and 4,4'-bpy is 4,4'-bipyridine, C(10)H(8)N(2)), in which each btec ligand links six copper(II) cations into a lamellar [Cu(6)(btec)(3)(H(2)O)(2)](n) subpolymer framework. There are two distinct diamine units and two distinct carboxylate units, with one of each lying across an inversion centre.
