catena-Poly[[[aqua­bis(acetato-κO)­copper(II)]-μ-1,3-di-4-pyridylpropane-κ²N:N′] monohydrate]

In the title complex, {[Cu(CH₃COO)₂(C₁₃H₁₄N₂)(H₂O)]·H₂O}_n, the Cu atom is five-coordinated in a distorted square-pyramidal geometry by one O atom of the coordinated water mol­ecule, two O atoms from two acetate anions and two N atoms from two 1,3-di-4-pyridylpropane (dpp) ligands. The dpp ligands bridge the Cu atoms to form a zigzag chain. The crystal structure involves O—H...O hydrogen bonds.

S1. Comment

The ligand 1,3-di-4-pyridylpropane (dpp) has been extensively studied in recent years due to its strong coordination capability and bridging function. Here we report the structure of a new coordination polymer (I) (Fig. 1). The polymeric chain is assembled of [Cu(C₁₃H₁₄N₂)(CH₃COO)₂(H₂O)].H₂O with the five coordinated Cu^II. The coordination sphere includes the coordinated water molecule, two carboxyl O atoms from two acetate anions and two pyridyl N from two 1,3-di-4-pyridylpropane(dpp) ligands (Table 1). The plane N1/O3/N2A/O1 defines the base of the pyramid while water O5 is the apex. The distance from Cu to the least-squares plane N1/O3/N2A/O1 is 0.1272 (3) Å. The dpp ligand acts as a bridging ligand linking neighbouring Cu^II atoms into a zigzag chain with the Cu1···Cu1 (-x + 7/4, y - 1/4, z - 3/4) separation distance of 12.851 (2) Å.

In the crystal structure of (I), there is π-π stacking interactions between the adjacent pyridine rings of neighbouring chains. The dihedral angle of aromatics involved in stacking is 8.788 (1) °. Interplanar average distance and ring-centroid separation distance are 3.441 (1) Å and 3.701 (4) Å, respectively. The chain structure is crosswise arranged into two-dimensional network (Fig. 2) by π-π stacking. The coordinated and uncoordinate water molecules, and carboxyl group take part in intermolecular hydrogen bonding (Table 2) stabilizing the structure.

S2. Experimental

The ligand dpp (1 mmol, 0.2 g) was dissolved in a mixture water - methanol (v/v 1:1, 20 ml). To this solution, Cu(CH₃COO)₂. 4H₂O (1 mmol, 0.26 g) was added and the resulting mixture was stirred and refluxed at 353 K for 3 h. Then the reaction mixture was cooled to room temperature. After filtration and evaporation in air for five days, dark-blue block-shaped crystals were obtained in the yield of 45%.

S3. Refinement

H atoms bonded to C atoms were positioned geometrically with C—H distance 0.93–0.97 Å, and treated as riding atoms with U_iso(H)=1.2U_eq(C). H atoms bonded to O atoms were located in a difference Fourier map and refined isotropically.

Special details

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.
