A novel mixed-valence copper complex, poly[[μ2-4,4′-bipyridine-μ3-pyridine-2,4,6-tricarboxylato-dicopper(I,II)] monohydrate]

In the title novel mixed-valence copper complex, {[Cu2(C8H2NO6)(C10H8N2)].H2O}n, the Cu(I) and Cu(II) ions are linked by 4,4'-bipyridine (bpy) and pyridine-2,4,6-tricarboxylate (ptc) ligands into corrugated layers, which are assembled via interlayer C-H...O hydrogen bonds to give a three-dimensional supramolecular architecture.
