Abstract
The title salt, [Cu(C2H3O2)(C12H12N2O2)2](C15H6N7O10)·H2O, comprises a [Cu(MeObpy)2(C2H3O2)]+ complex cation (where MeObpy = 4,4'-dimeth-oxy-2,2'-bi-pyridine), a non-coordinating pnpz- anion (pnpz- = 3,5-bis-(2,4-di-nitro-phen-yl)-4-nitro-pyrazolate) and one inter-stitial water solvent mol-ecule. The central CuII atom is five-coordinate, with a coordination environment inter-mediate between square-pyramidal and trigonal-bipyramidal, defined by two chelating 4,4'-dimeth-oxy-2,2'-bi-pyridine 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 mol-ecules (aceto-nitrile and water) was treated with the SQUEEZE routine in PLATON [Spek (2015 ▸). Acta Cryst. C71, 9-18]. Their contribution was not taken into account during refinement.
