Bis(2,2'-bipyridine N-oxide-²O,N)copper(II) -octamolybdate

J.-H. Yuan, C. Wang and Z.-Y. Sun

Abstract: The title compound, bis(2,2'-bipyridine N-oxide-²N,O)hexacosaoxocopper(II)molybdenum(IV), [Cu₂Mo₈O₂₆(C₁₀H₈N₂O)₄], was obtained by a hydrothermal reaction. The Cu atom is coordinated by two O atoms and two N atoms from two 2,2'-bipyridine N-oxide (L) ligands and one terminal O atom from one [-Mo₈O₂₆]^4- cluster with a square-pyramidal coordination geometry; the apical Cu-O bond distance is significantly longer than Cu-O bond distances in the basal plane. Two terminal O atoms of the (-Mo₈O₂₆)^4- cluster link two [Cu(L)₂]²⁺ units, forming a centrosymmetric dimer.
