(Received 31 July 2012; accepted 6 August 2012; online 11 August 2012)

The AgI atom in the polycationic salt, {[Ag(C11H11N3O)]NO3}n, shows a linear coordination [N—Ag—N = 175.0 (2)°]; the polymeric nature arises from bridging by the pyrazine portion of the ligand, resulting in chains extending parallel to [100]. The NO3 counter-ions surround the polymeric chain and inter­act only weakly with it [Ag⋯O = 2.701 (4) and 2.810 (5) Å]. Adjacent chains are linked into a three-dimensional network by O—H⋯O and N—H⋯O hydrogen bonds.

Supporting information


Comment top

A recent study reports 2-[(pyrazin-2-ylamino)methyl]phenol, a reduced Schiff-base that possesses an acidic phenolic group (Gao & Ng, 2012). The reaction with silver nitrate yields polycationic [Ag(C11H11N3O)]n nNO3 (Scheme I). The polymeric nature arises from bridging by the pyrazine portion of the ligand. The counterions surround the chain and interact only weakly with it [Ag···O 2.701 (4), 2.810 (5) Å] (Fig. 1). Adjacent chains are linked into a three-dimensional network by O–H···O and N–H···O hydrogen bonds (Table 1).

Experimental top

An acetonitrile solution (10 ml) of silver nitrate (1 mmol) was added to a methanol solution (5 ml) of 2-[(pyrazin-2-ylamino)methyl]phenol (1 mmol). The solution was filtered and then side aside, away from light, for the growth of crystals. Colorless crystals were obtained after several days.

Refinement top

Hydrogen atoms were placed in calculated positions (C–H 0.93–0.97, N–H 0.88, O–H 0.84 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2–1.5U(C,N,O).
