(Received 13 November 2007; accepted 30 November 2007; online 6 December 2007)

In the title compound, {[Ag(C12H11N3O)]NO3·H2O}n, the Ag atom is coordinated by two N atoms from the heterocyclic ligand, giving a linear polycationic chain. Two long Ag⋯Onitrate inter­actions [2.667 (3) and 2.840 (3) Å] result in a three-dimensional network. The water mol­ecule consolidates the network structure by forming hydrogen bonds, one to the polycationic chain and one to the nitrate anion.

Comment top

The reactions of silver(I) salts with flexible pyridyl type ligands have received considerable attention (Cordes et al., 2007; Kumar et al., 2006; Tong et al., 2002). Here, we report a new silver(I) complex (Fig. 1), which was prepared by the reaction of N-(3-pyridinylmethyl)-4-pyridine-carboxamide acting as a bidentate bridge ligand with AgNO3. In the cation, the Ag(I) atom is in a linear coordination environment and the Ag1—N1A and Ag1—N3 bond length are 2.152 (3) and 2.157 (3) Å, respectively. The N3—Ag1—N1i (i = -1 + x, 0.5 - y, 1/2 + z) bond angle is 172.55 (15) °, indicating that the N–Ag–N skeleton that gives rise to a chain structure is distorted by the presence of two Ag···Onitrate interactions. If these are regarded as formal bonds, the compound may be described as a three dimensional network structure (Fig. 2).

Experimental top

An aqueous solution (5 ml) of silver nitrate (1.0 mmol) was layered carefully over a methanol (5 ml) solution of N-(4-pyridylmethyl)-4-pyridinecarboxamide (1.0 mmol) in a tube, which was covered and kept away from light. Colorless crystals were obtained after two weeks. These were washed with methanol and collected in 50% yield. CHN elemental analysis: found C 35.86, H 3.55, N 13.79%; calc. for C12H13AgN4O5: C 35.93, H 3.27, N 13.96%.

Refinement top

All H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H distances of 0.93–0.97 Å, N—H distances of 0.86 Å and OW1—H distances of 0.85 Å, and with Uiso(H) = 1.2Ueq(C, N or O).

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
