| Summary: | In the title salt, [Cu(NO3)(C7H6N 2)4]NO3, one nitrate anion is coordinated to the Cu II atom, which is also coordinated by the N atoms of four N-heterocycles. The geometry at the metal atom is a square pyramid in which the O atom of the anion occupies the apical position [Cu - O = 2.468 (5) and 2.590 (7) Å in the two independent formula units]. The cation lies on a twofold rotation axis; the coordinated nitrate anion is also disordered about this symmetry element. The lattice anion is also disordered about a twofold rotation axis. In the crystal, the cations are linked to the coordinated and free anions by N - H⋯O hydrogen bonds. |
