Abstract top

In the title compound, {[Ag(C10H14N4)(H2O)](C14H8O4)0.5·2H2O}n, the AgI ion is three-coordinated by two N atoms from two independent 1,1'-(butane-1,4-diyl)di-1H-imidazole (BBI) ligands and one water O atom in a distorted T-shaped coordination geometry. The biphenyl-4,4'-dicarboxylate (BPDC) dianions do not coordinate to AgI ions but act as counter-ions. The AgI ions are linked by BBI ligands, forming a zigzag chain. These chains are linked into a two-dimensional supramolecular architecture by O-H...O hydrogen-bonding interactions between water molecules and carboxylate O atoms of the BPDC dianions.

Comment top

Design of effective ligands and the proper choice of metal centers are the keys to design and construct novel metal-organic frameworks (Kitagawa et al., 2004; Ma et al., 2009). These complexes can be specially designed by careful selection of metal cations with preferred coordination geometries, nature of the anions, structures of connecting ligands, and the reaction conditions (Li et al., 2005). In this contribution, we selected biphenyl-4,4'-dicarboxylic acid (H2BPDC) as an organic carboxylate anion and 1,1'-(butane-1,4-diyl)di-1H-imidazole (BBI) as a N-donor neutral ligand, generating a coordination compound, [Ag(BPDC)0.5(H2O)(BBI)].2H2O, which is reported here.

In the title compound, each AgI ion is three-coordinated by two N atoms from two independent half-units of the BBI ligands and one water molecule in a distorted T-shaped coordination geometry. The Ag—N and Ag—O distances are comparable to those found in other crystallographically characterized AgI complexes (Ma et al., 2005). The adjacent AgI ions are linked by BBI ligands to give a one-dimensional zigzag chain. Biphenyl-4,4'-dicarboxylate anions, acting as counterions, have no contribution to the formation of the final structure (Fig. 1). However, there are intermolecular O—H···O hydrogen bonding interactions among water molecules and BPDC anions. These hydrogen bonds extend zigzag chains into a two-dimensional supramolecular architecture.

Experimental top

To a mixture of biphenyl-4,4'-dicarboxylic acid (0.0484 g, 0.2 mmol) and Ag2CO3 (0.0275 g, 0.1 mmol) in water was added 1,1'-(butane-1,4-diyl)di-1H-imidazole (0.2 mmol, 0.038 g) with constant stirring. After the sample was stirred for 10 min, the precipitate was dissolved by dropwise addition of aqueous NH3 solution. Colourless crystals were obtained from the filtrate by slow evaporation after standing in the dark for several days.

Refinement top

Independent atom C5 of the butyl linkage is disordered over two positions with occupancies of 0.852 (8) and 0.148 (8). H atoms of the water molecules were located in a difference Fourier map and refined with an O—H distance restraint of 0.85 (2) Å and with Uiso(H) = 1.5Ueq(O). H atoms on C atoms were generated geometrically and refined as riding atoms with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C).

Special details top

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
