2,4-Dibromo-6-((pyridine-2-ylmethylamino)methyl)phenol (0.372 g, 1 mmol) was added to a methanol solution (20 ml) of CuCl2·2H2O (0.170 g, 1 mmol) with stirring. The resulting solution was left to stand at room temperture and blue blocks of (I) were obtained after several days.
All H-atoms bound to carbon were refined using a riding model [C—H = 0.93 Å, Uiso(H) = 1.2Ueq(C)]. The amino H atom was located in a difference map and it sposition was freely refined with Uiso(H) = 1.2 Ueq(N).
Copper(II) complexes with various organic ligands have been a subject of intense study because of their important biological properties (Solomon et al., 1996). Here, we report the synthesis and structure of the new title complex, Cu(dmp)Cl, (I), where dmp is 2,4-dibromo-6((pyridine-2-ylmethylamino)methy)phenol.
Selected bond lengths are listed in Table 1. The CuII atom is four-coordinated by one pyridine N atom, one amine N atom and one phenolate O atom from the ligand and one chloride ion in a distorted square-planar arangement (Fig. 1). The metal to ligand-atom distances in (I) are similar to the ones found in bis[2,4-dibromo-6((pyridnine-2-ylmethylamino)methy) phenolato]bis[nitratocopper(II)] (Ma et al., 2007).
An N—H···O hydrogen bond (Table 2) helps to stabilize the packing in (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. |

Copper(II) complexes with various organic ligands have been a subject of intense study because of their important biological properties (Solomon et al., 1996). Here, we report the synthesis and structure of the new title complex, Cu(dmp)Cl, (I), where dmp is 2,4-dibromo-6((pyridine-2-ylmethylamino)methy)phenol.
Selected bond lengths are listed in Table 1. The CuII atom is four-coordinated by one pyridine N atom, one amine N atom and one phenolate O atom from the ligand and one chloride ion in a distorted square-planar arangement (Fig. 1). The metal to ligand-atom distances in (I) are similar to the ones found in bis[2,4-dibromo-6((pyridnine-2-ylmethylamino)methy) phenolato]bis[nitratocopper(II)] (Ma et al., 2007).
An N—H···O hydrogen bond (Table 2) helps to stabilize the packing in (I).
