A new hybrid organic-inorganic chain: [(phen)Cu-[mu]-([kappa]²O:O'-VP₂O₁₀H₃)₂-Cu(phen)]_n

The structure of the title compound, poly[(dihydrogen­phosphato-[kappa]O)([mu]₃-hydrogenphosphato)di-[mu]-oxido-(1,10-phenanthroline)copper(II)vanadium(V)], [CuV(HPO₄)(H₂PO₄)O₂(C₁₂H₈N₂)]_n, is defined by [(phen)Cu-[mu]-([kappa]²O:O'-VP₂O₁₀H₃)₂-Cu(phen)] units (phen is 1,10-phenanthroline), which are connected to neighbouring units through vanadyl bridges. Neighbouring chains have no covalent bonds between them, although they inter­digitate through the phen groups via [pi]-[pi] inter­actions.
