L (0.100 g, 0.17 mmol) dissolved in hot ethanol (15 ml) was added to a solution of CuCl2.2H2O (0.030 g, 0.17 mmol) in hot water (10 ml). After stirring for 30 min, the mixture was filtered. Blue single crystals of the title compound were obtained after several days at room temperature.
All H atoms bound to C atoms were positioned geometrically and refined as riding, with C—H = 0.93Å (CH) and 0.97Å (CH2) and Uiso(H) = 1.2Ueq(C). The H atoms bound to N atoms and belonging to water molecule were located in a difference Fourier map and refined with Uiso(H) = 1.4Ueq(N) and Uiso(H) = 1.3Ueq(O), respectively.
The use of macrocyclic ligands for the formation of selective metal complex has received considerable attention over many years (Davis et al., 1995). The method for the synthesis of the title complex has been reported (Adam et al., 1981). However, to the best of our knowledge, the crystal structure has not been reported yet.
The molecule of the title compound is composed of two CuII atoms, four Cl- atoms, a 3,4:9,10:17,18:23,24-tetrabenzo-1,12,15,26-tetraaza- 5,8,19,22-tetraoxacyclooctacosane (L) ligand and two water molecules (Fig.1). It is a centrosymmetric molecule. Each CuII atom shows a tetragonal-pyramidal coordination geometry, formed by two Cl- atoms, two N atoms from L and one water molecule. The bond distances and angles show normal values (Table 1) (Higa et al., 2007; Jiang et al., 2007; Michalska et al., 2007; Zhou et al., 2007). There are hydrogen-bonding interactions in the crystal structure. As shown in Fig. 2 and in Table 2, there are two O—H···Cl hydrogen bonds between the water molecule and Cl- atoms, leading to a one-dimensional supramolecular structure (Barczynśki et al., 2007).

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. |

The use of macrocyclic ligands for the formation of selective metal complex has received considerable attention over many years (Davis et al., 1995). The method for the synthesis of the title complex has been reported (Adam et al., 1981). However, to the best of our knowledge, the crystal structure has not been reported yet.
The molecule of the title compound is composed of two CuII atoms, four Cl- atoms, a 3,4:9,10:17,18:23,24-tetrabenzo-1,12,15,26-tetraaza- 5,8,19,22-tetraoxacyclooctacosane (L) ligand and two water molecules (Fig.1). It is a centrosymmetric molecule. Each CuII atom shows a tetragonal-pyramidal coordination geometry, formed by two Cl- atoms, two N atoms from L and one water molecule. The bond distances and angles show normal values (Table 1) (Higa et al., 2007; Jiang et al., 2007; Michalska et al., 2007; Zhou et al., 2007). There are hydrogen-bonding interactions in the crystal structure. As shown in Fig. 2 and in Table 2, there are two O—H···Cl hydrogen bonds between the water molecule and Cl- atoms, leading to a one-dimensional supramolecular structure (Barczynśki et al., 2007).
