Abstract top

In the title compound, [Ag(NO3)(C18H14N4)]n, the AgI atom is coordinated by two N atoms from two N,N'-bis(3-pyridylmethylidene)benzene-1,4-diamine (bpbd) molecules and two O atoms from a bidentate nitrate anion. The bpbd molecules bridge the Ag atoms into a chain. Two adjacent chains are further connected by Ag...Ag interactions [3.1631 (8) Å], forming a double-chain structure. A [pi]-[pi] interaction [centroid-centroid distance = 3.758 (3) Å] occurs between the double chains. Interchain C-H...O hydrogen bonds are observed.

Comment top

Bipyridine-type ligands have been extensively investigated in recent years, owing to their simple structures, readily availabilities and more predictable formation of network structures (Biradha et al., 2006; Cunha-Silva et al., 2006; Lu et al., 2002). Moreover, when introducing double Schiff-base, a great deal of metal–organic frameworks with unusual network patterns and novel properties can be achieved due to the specific geometry including the different relative orientation of N-donors and the zigzag conformation of the space moiety between the two terminal coordination groups (Ye et al., 2004).

Herein, we choose 3,3'-bipyridine-type Schiff-base as an organic linking ligand. In this simple compound, N═C—H group can act as a hydrogen bonding donor and the pyridyl N atom as an acceptor. In the title complex, the ligand takes a bidentate bridging coordination fashion and links two AgI centers with two pyridyl N atoms (Fig. 1), forming a zigzag chain, with Ag—N distances being 2.162 (2) and 2.163 (2) Å (Table 1). The two neighboring Ag atoms exhibit an Ag···Ag interaction, with a distance of 3.1631 (8) Å. The Ag atoms are also coordinated by distant nitrate O atoms [Ag—O = 2.731 (3) and 2.704 (3) Å], leading to a deviation from linearity [N—Ag—N = 159.44 (9)°]. Two adjacent chains are connected by the Ag···Ag interactions into a double-chain structure (Fig. 2). A π–π interaction [centroid–centroid distance = 3.758 (3) Å] occurs between the double-chains. Interchain C—H···O hydrogen bonds are observed (Table 2).

Experimental top

The ligand L was prepared according to the previous method (Ye et al., 2004). 1,4-Diaminobenzene (2.14 mg, 10 mmol) was dissolved in methanol (20 ml), followed by addition of 3-pyridinecarboxaldehyde (4.24 mg, 40 mmol). The mixture was stirred at room temperature for 2 h and filtered. The resulting yellow crystalline solid was washed with methanol several times and dried in air. A solution of AgNO3 (33.9 mg, 0.2 mmol) in acetonitrile (10 ml) was slowly layered onto a solution of L (117 mg, 0.625 mmol) in methylene chloride (10 ml). Diffusion between the two phases over a week produced colorless crystals.

Refinement top

H atoms were placed at calculated positions and refined as riding atoms, with H—C = 0.93 Å and with Uiso(H) = 1.2Ueq(C).
