In the title compound, [Cu2Cl2(C10H12NO3)2]·CH3OH, each of the two CuII atoms is bound to two O and one N atoms of the bis-chelating monoanionic Schiff base and two bridging chloride ligands. The metal atoms each show a distorted square-pyramidal coordination geometry. Intramolecular O—H⋯O hydrogen bonds occur. In the crystal, O—H⋯O hydrogen bonds join the components into a chain extending along the a axis.

3-(2-Hydroxybenzylideneamino)propane-1,2-diol (0.0384 g, 0.2 mmol) and NaOH (0.0080 g, 0.2 mmol) were dissolved in methanol (10 ml). A solution of CuCl2.2H2O (0.0341 g, 0.2 mmol) in methanol (10 ml) was added drop-wise into the previous mixture. The resulting solution was stirred at room temperature for two hours and then filtered. Green crystals suitable for X-ray crystallographic analysis were obtained by slow evaporation of the filtrate after one week.
All H atoms bound to C and O atoms were placed in calculated positions and treated as riding on their parent atoms, with C—H = 0.93-0.98 Å, Uiso(H) = 1.2 or 1.5 Ueq(C) and O—H = 0.82 Å, Uiso(H) = 1.5 Ueq(O).

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

Design and investigation of polynuclear transition metal complexes have received a great attention. The motivation in this field is justified not only by architectural beauty of the structures, but also by intellectual challenge of understanding the fundamental correlation between structures and magnetic properties (Yang et al., 2010). Crucial to such efforts is the continuing development of new synthetic procedures of polynuclear transition metal species.
In order to synthesize new polynuclear paramagnetic clusters, we have recently begun to employ an asymmetric Schiff-base ligand, 3-(2-hydroxybenzylideneamino)-propane-1,2-diol, which contains a tetradentate {NO3} donor set and three hydroxyl groups that possess chelating and bridging capabilities. We believe that the four potential incorporable sites and multiple coordination modes will make the ligand a good candidate for the achievement of new polynuclear complexes. Here, we present the synthesis and structure of a new dinuclear copper complex, namely [Cu2(C10H12NO3)2Cl2].CH3OH (Scheme 1).
X-ray characterization of the title complex reveals that the dinuclear unit consists of two copper(II) atoms linked by two chloride ions. Each copper atom is coordinated by N-O-O atoms from a Schiff-base ligand and two chloride ions, providing a distorted square pyramidal environment (Fig. 1). Hydrogen bonds connect the complex into a chain extended along the a axis (Fig. 2).
