A mixture of CuCl2.2H2O (0.5 mmol), H2L (0.5 mmol), Pyphen (0.5 mmol), and H2O (500 mmol) was adjusted to pH = 5.5 by addition of aqueous NaOH solution, and heated at 453 K for six days. After the mixture was slowly cooled to room temperature, blue blocks of (I) resulted.
The C-bound H atoms were positioned geometrically (C—H = 0.93 Å) and refined as riding, with Uiso(H) = 1.2Ueq(C). The water H-atoms were located in a difference Fourier map, and their positions were freely refined with Uiso(H) = 1.2Ueq(O).
Studies on metal dicarboxylato complexes with heteroaromatic N-donor chelating ligands are of current interest (Chen & Liu, 2002). Pyrazino[2,3-f][1,10]phenanthroline (Pyphen) as a new phen derivative possesses an extended aromatic system. We selected 4,4'-oxybis(benzoic acid) (H2L) as a linker and Pyphen as a secondary chelating ligand, and in combination with Cu2+ ions, generaed the new coordination polymer, [Cu(L)(Pyphen)].H2O, (I), which is reported here.
In compound (I) the CuII atom is four-coordinated by two Pyphen N atoms and two carboxylate O atoms, and exhibits a distorted square-planar coordination sphere (Table 1, Fig. 1). The L ligands link the CuII atoms to generate a distinctive helical chain structure (Fig. 2). The Pyphen ligands are attached on both sides of the chains. The neighbouring chains are linked through π-π interactions between Pyphen ligands with a π-π stacking distance of ca 3.44 Å, resulting in a two-dimensional supramolecular structure (Fig. 3). Finally, O—H···O hydrogen bonds involving the water molecule and carboxylate O atom acceptors (Table 2) complete the structure of (I).

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. |

Studies on metal dicarboxylato complexes with heteroaromatic N-donor chelating ligands are of current interest (Chen & Liu, 2002). Pyrazino[2,3-f][1,10]phenanthroline (Pyphen) as a new phen derivative possesses an extended aromatic system. We selected 4,4'-oxybis(benzoic acid) (H2L) as a linker and Pyphen as a secondary chelating ligand, and in combination with Cu2+ ions, generaed the new coordination polymer, [Cu(L)(Pyphen)].H2O, (I), which is reported here.
In compound (I) the CuII atom is four-coordinated by two Pyphen N atoms and two carboxylate O atoms, and exhibits a distorted square-planar coordination sphere (Table 1, Fig. 1). The L ligands link the CuII atoms to generate a distinctive helical chain structure (Fig. 2). The Pyphen ligands are attached on both sides of the chains. The neighbouring chains are linked through π-π interactions between Pyphen ligands with a π-π stacking distance of ca 3.44 Å, resulting in a two-dimensional supramolecular structure (Fig. 3). Finally, O—H···O hydrogen bonds involving the water molecule and carboxylate O atom acceptors (Table 2) complete the structure of (I).
