The Ag atom in the title compound, [Ag(C13H10N2)2]NO3, shows an approximately linear coordination [N–Ag–N 162.6 (4)°]. The coordination geometry is distorted towards square-planar owing to two long Ag⋯O interactions [Ag⋯O = 2.634 (15) and 2.861 (13) Å]. In the the Ag atom lies on a special position of 2 the nitrate anion is disordered about the special position. The crystal under investigation was a racemic twin with a 33% minor twin component.

3-(2-Naphthyl)pyrazole was prepared according to the literature method (Yang & Raptis, 2003). An acetonitrile solution (2 ml) of silver nitrate (0.02 mmol, 3.4 mg) was mixed with an ethanol solution (1 ml) of 3-(2-naphthyl)pyrazole (0.02 mmol, 4 mg). The pH value of the mixture was adjusted to about 5 by dilute nitric acid. The resulting solution was allowed to evaporate for two weeks to yield colorless crystals in 60% yield.
The measurements are complete to 94% at a 2θ of 55 °, but are complete to 98% at a 2θ of 50 °.
The nitrate group is disordered about the twofold rotation axis; the anion was allowed to refine off the
The three N–O distances were restrained to within 0.01 Å of each other, as were the three O···O distances. The four atoms were restrained to be nearly planar, and their anisotropic temperature factors were restrained to be nearly isotropic. Carbon-bound H atoms were placed in calculated positions [C—H = 0.93, N–H 0.89 Å; U(H) = 1.2Ueq(C,N)].The crystal under investigation is a racemic twin; the explicit
