Abstract

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⋯O_nitrate 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

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···O_nitrate interactions. If these are regarded as formal bonds, the compound may be described as a three dimensional network structure (Fig. 2).

Experimental

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%.
