A mixture of L (0.30 g, 1 mmol), AgNO3 (0.17 g, 1 mmol), fumaric acid (0.12 g, 1 mmol) and H2O (10 ml) was stirred for 1 h and then sealed in a 25 ml Teflonlined stainless steel container. The container was heated to 423 K and held at that temperature for 72 h, then cooled to room temperature at a rate of 10 K h-1. Colorless crystals of the title compound were collected in 56% yield based on Ag.
All H atoms bonded to C atoms were positioned geometrically and refined as riding atoms with C—H = 0.93 A ° and Uiso(H) = 1.2Ueq(C). The water H-atoms were located in a difference Fourier map, and were refined freely with Uiso(H) = 1.5Ueq(O).

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 design and synthesis of supramolecular complexes exhibiting novel structures and properties has provided exciting new prospects for chemists (Fujita et al., 1995; Yaghi et al., 1995; Zaworotko & Moulton, 2001). Among various supramolecular compounds, Ag(I) compounds are attractive because of their diverse structural types (Corespo et al., 1998). In this paper, we isolated a new Ag supramolecular compound, {[Ag(L)(fum)0.5].H2O}n, constructed using 1,4-bis(pyridin-3-ylmethoxy)benzene (L) and fumarate (fum) ligands.
In the title structure, each AgI cation is four-coordinated and shows a tetrahedral geometry, surrounded by two N atoms from different L ligands and two carboxylate oxygen atoms from different fum anions (Fig. 1). The dihedral angle between two pyridine rings in the same L ligand is 23.6 (5)°. All bond distances and angles are normal (Allen et al., 1987). The L ligands exhibit bis-monodentate coordination modes and links AgI cations to generate an extended chain, which is further linked by fumarate anions to generate a double chainlike structure (Fig. 2). The lattice water molecules donate hydrogen bonds to carboxylate oxygen atoms of fumarate anions from adjacent double-chains, thus forming an intereting two-dimensional supramolecular structure (Fig. 3).
