Abstract

The structure of the title compound, (C(10)H(9)N(2))[Bi(NO(3))(4)(C(10)H(8)N(2))], consists of 2-(2-pyrid-yl)pyridinium cations and anions [Bi(NO(3))(4)(C(10)H(8)N(2))](-). The Bi(3+) ion lies on the twofold axis. It is coordinated by two nitro-gen atoms from one 2,2'-bipyridine ligand and eight oxygen atoms from four NO(3) (-) anions. The disordered cation is positioned at the inversion centre. The [Bi(NO(3))(4)(C(10)H(8)N(2))](-) anions and 2-(2-pyrid-yl)pyridinium cations are connected via N-H⋯O hydrogen bonds into chains. Moreover, these chains are further linked into a two-dimensional layered structure through π-π stacking inter-actions between bipyridine ligands along the c axis [centroid-centroid distance = 2.868 (4) Å].
