Abstract

In the title compound, [Ag₂(C₆H₆NO₃S)₂(C₁₀H₈N₂)₂]_n, the Ag^I atom is four-coordinated by two N atoms from two symmetry-related 4,4′-bipyridine (bipy) and two O atoms from two independent 4-aminobenzenesulfonate (ABS) ligands. The two inter-chain Ag^I atoms are bridged by two independent ABS ligands through weak Ag—O bonds and Ag⋯Ag attractions, forming a ladder-like chain coordination polymer [Ag₂(ABS)₂(bipy)₂]_n parallel to [001], which is further linked to generate a two-dimensional structure via N—H⋯O hydrogen-bonding interactions.

Comment

In the construction of inorganic–organic supramolecular complexes, the Ag^I is often a favorable candidate due to its flexible coordination modes and Ag–Ag attractions (Liu et al., 2005; Dong et al., 2005; Bi et al., 2003; Ding et al., 2005; Yang et al., 2004). Bipy (4,4'-bipyridine) and ABS (4-aminobenzenesulfonic acid) are useful building blocks because they contain bifunctional groups, which can coordinate with metal ions in various coordination modes through the oxygen atoms of sulfonic group and the nitrogen atoms of pyridyl ring (Liu et al., 2005; Feng et al., 2003; Wei et al., 2004). Therefore, we also extended these investigations to the use of the ligand ABS and obtained various framework structures. In this paper, we report the structure of the title compound, (I).

As illustrated in Fig. 1, each Ag^I atom in the title compound is four-coordinated by two nitrogen atoms from bipy (Ag1—N1 = 2.187 (3) Å, Ag1—N2 = 2.179 (3) Å) and two oxygen atoms from two independent ABS (Ag1—O1 = 2.572 (2) Å and Ag1—O1# = 2.654 (2) Å, # 1 - x, -y, 1 - z). These coordination modes are different from those found in structures similar to (I), wherein both oxygen atoms of acetic acid are linked to Ag atoms (Sampanthar & Vittal, 2000; Tong et al., 2000). The two inter-chain Ag^I atoms are bridged by two independent ABS ligands through week Ag—O bonds and Ag–Ag attractions (Ag1–Ag1# = 3.903 Å, # 1 - x, -y, 1 - z), forming a one-dimensional ladder-like chain coordination polymer [Ag₂(bipy)₂(ABS)₂]_n with periodical distance of 11.43 Å, which is further linked to generate a two-dimensional structure via hydrogen-bonding interactions with an average O–O distance of 2.877 Å (Fig. 2).

Experimental

To a mixture of bipy (0.032 g, 0.2 mmol), ABS (0.017 g, 0.1 mmol) and Ag₂O (0.028 g, 0.05 mmol) in CH₃OH (10 ml) was added ammonia water resulting in a clear solution. After heating at 323 K for 0.5 h, the solution was evaporated slowly in the dark. Five days later, slightly yellow crystals were formed from the solution.
