A hybrid bimetallic complex from regioselective in situ ligand oxidation: poly[(--octamolybdato-²O:O)bis[-4-(2-pyridyl)pyridinium-3-olato-³N,O:O]bis[4-(2-pyridyl)pyridinium-3-olato-²N,O]dicopper(II)]

Abstract: The title compound, [Cu₂(C₁₀H₈N₂O)₄(-Mo₈O₂₆)]_n, is a one-dimensional coordination polymer containing octahedrally coordinated Cu^II atoms, each of which is bound to three O atoms and two N atoms from three distinct regioselectively oxidized 2,4'-bipyridinium ligands and one O atom from a centrosymmetric -octamolybdate anion. The 4'-position N atoms within the ligands, as quaternary N atoms, are uncoordinated. [Cu₂(2'-O^--2,4'-bpyH⁺)₄]⁴⁺ dimeric cations are linked through exobidentate -octamolybdate anions into polymeric chains running along the [011] direction. N-HO and C-HO interactions connect adjacent chains into a three-dimensional network.
