Bis(2,2′-bipyridineN-oxide-κ2O,N)copper(II) β-octamolybdate

Abstract

The title compound, bis­(2,2′-bipyridine N-oxide-κ2N,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 [β-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 (β-Mo8O26)4− cluster link two [Cu(L)2]2+ units, forming a centrosymmetric dimer.
