Abstract
The title salt, [Cu(C 2 H 3 O 2 )(C 12 H 12 N 2 O 2 ) 2 ](C 15 H 6 N 7 O 10 )·H 2 O, comprises a [Cu(MeObpy) 2 (C 2 H 3 O 2 )] + complex cation (where MeObpy = 4,4′-dimethoxy-2,2′-bipyridine), a non-coordinating pnpz − anion (pnpz − = 3,5-bis(2,4-dinitrophenyl)-4-nitro-pyrazolate) and one interstitial water solvent molecule. The central Cu II atom is five-coordinate, with a coordination environment intermediate between square-pyramidal and trigonal-bipyramidal, defined by two chelating 4,4′-dimethoxy-2,2′-bipyridine ligands and one O atom of a monodentate acetate anion at 1.969 (3) Å. Two Cu—N bond lengths, 1.985 (3) and 2.006 (3) Å, are similar and shorter than the other two Cu—N bond lengths of 2.061 (3) and 2.148 (4) Å. In the crystal, the electron density from a region of disordered solvent molecules (acetonitrile and water) was treated with the SQUEEZE routine in PLATON [Spek (2015). Acta Cryst . C 71 , 9–18]. Their contribution was not taken into account during refinement.
