In the title complex, [Ag2(C12H8N2O4)(C10H8N2)2]·2H2O, the AgI ion is three-coordinated by two N atoms from a chelating 2,2′-bipyridine ligand and one N atom from an imide ligand in a Y-shaped fashion. The imide ligand and the complex lie on a twofold rotation axis. The ligand bridges two AgI ions, forming a dinuclear complex. In the crystal, O—H⋯O hydrogen bonds link the lattice water molecules and the complex molecules into a ribbon-like structure along [001]. π–π interactions are observed between the pyridine rings [centroid–centroid distance = 3.8289 (14) Å].

A mixture of bicyclo[2,2,2]oct-7-ene-2,3,5,6-tetracarboxylic dianhydride (0.1 mmol, 0.025 g), 2,2'-bipyridine (0.2 mmol, 0.080 g), silver nitrate (0.2 mmol, 0.034 g) and H2O (15 ml) was stirred for ten minutes. Dilute ammonia was dropwised into the mixture until the mixture turned to transparent. Colorless block crystals of the title compound were isolated after the evaporation of ammonia.
H atoms on C atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 and 0.98 Å and with Uiso(H) = 1.2Ueq(C). H atoms bonded to O atoms were located in a difference Fourier map and refined with O—H distance restraints of 0.85 (2) Å and with Uiso(H) = 1.5Ueq(O).
The assembly of mixed-ligand coordination polymers has attracted great attention due to their intriguingly complicated architectures and potential applications in adsorption, separation and magnetism (Song et al., 2012; Wang, 2010). Molecular building blocks associated with polydentate
are widely used in chiral catalysis, optoelectronic materials, hematopathology and medicine (Liao et al., 2008; Wang et al., 2009). In our laboratory, we synthesized a new silver(I) complex constructed by an amide molecule in combination with 2,2-bipyridine as ancillary ligand.In the title complex, the amide ligand lies on a twofold rotation axis and bridges two 2,2'-bipyridine-chelated AgI atoms. The AgI atom is three-coordinated by two N atoms of a 2,2'-bipyridine ligand [Ag—N distances = 2.3510 (18) and 2.2380 (18) Å] and one N atom from an amide ligand [Ag—N distance = 2.1123 (17) Å]. In the crystal, O—H···O hydrogen bonds link the uncoordinated water molecules and the complex molecules into a ribbon-like structure. π–π interactions between the pyridine rings are observed [centroid–centroid distance = 3.8289 (14) Å].

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 > σ(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. |

The assembly of mixed-ligand coordination polymers has attracted great attention due to their intriguingly complicated architectures and potential applications in adsorption, separation and magnetism (Song et al., 2012; Wang, 2010). Molecular building blocks associated with polydentate carboxylic acids are widely used in chiral catalysis, optoelectronic materials, hematopathology and medicine (Liao et al., 2008; Wang et al., 2009). In our laboratory, we synthesized a new silver(I) complex constructed by an amide molecule in combination with 2,2-bipyridine as ancillary ligand.
In the title complex, the amide ligand lies on a twofold rotation axis and bridges two 2,2'-bipyridine-chelated AgI atoms. The AgI atom is three-coordinated by two N atoms of a 2,2'-bipyridine ligand [Ag—N distances = 2.3510 (18) and 2.2380 (18) Å] and one N atom from an amide ligand [Ag—N distance = 2.1123 (17) Å]. In the crystal, O—H···O hydrogen bonds link the uncoordinated water molecules and the complex molecules into a ribbon-like structure. π–π interactions between the pyridine rings are observed [centroid–centroid distance = 3.8289 (14) Å].
