title: Diammonium bis-[(2-amino-acetato-κN,O)(2,2'-bipyridine-κN,N')(N,N-dimethyl-formamide-κO)copper(II)] hexa-cosa-oxidoocta-molybdate(VI).
abstract: The title compound, (NH(4))(2)[Cu(C(2)H(4)NO(2))(C(10)H(8)N(2))(C(3)H(7)NO)](2)[Mo(8)O(26)], contains a centrosymmetric β-type octa-molybdate anion, two copper(II) complex cations and two ammonium ions. The Cu(II) atom is coordinated in a square-pyramidal geometry by a 2,2'-bipyridine and a 2-amino-acetate ligands in the basal plane and by an O atom of N,N-dimethyl-formamide in the apical position. The anions and cations are linked by N-H⋯O hydrogen bonds into a three-dimensional network.
