The title compound, [Cu(C13H8N5O)Cl]n, has a chain structure parallel to [100] with Cu2+ cations in a trigonal–bipyramidal coordination environment. The ligand adopts a tridentate tripyridyl coordination mode and a chloride ion acts as a bridge. The chains are linked via weak C—H⋯O and C—H⋯Cl hydrogen bonds into a three-dimensional supramolecular network.

The ligand 4,6-bis(2-pyridyl)-1,3,5-triazin-2-ol was prepared according to previously reported procedures (Wieprecht et al., 2005), yield 56%. The ligand (0.125 g, 0.5 mmol), CuCl2(0.07 g, 0.5 mmol), 7 ml distilled water and 7 ml ethanol were put into a 25 ml Teflon-lined Parr. The mixture was heated to 100 °C for 48 h, and then cooled to room temperature at a rate of 5 °C/h. The obtained mixture was filtered and green crystals were obtained.

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. |

The rigid multidentate polypyridyl ligands containing a triazine ring as a bridge have attracted greatly our attention due to their coordination diversity (Zhou, Li, Zheng et al., 2006; Zhou, Li, Wu et al. 2006). Although coordination chemistry of the symmetrical ligands like TPT has been well explored, the observations on the asymmetric ligands containing triazine ring are still rare. As a contribution to the synthesis and structural studies of coordination abilities of 4,6-bis(2-pyridyl)-1,3,5-triazin-2-ol ligand (Wieprecht et al., 2005; Cao et al., 2008, 2009), I present here the crystal structure of the title compound (Fig. 1)- a new copper(II) complex with the ligand. Within the title compound, the copper(II) center is five-coordinated respectively by three N atoms [the distances of Cu—N are in the range of 1.896 (2) - 2.049 (2) Å] from the ligand and two Cl atoms [the bond lengths of Cu—Cl are 2.224 (1) Å and 2.778 (2) Å]. The complex is a chain structure, in which the ligand adopts a tridentate tripyridyl coordination mode and the chloride ion acts as a bridge (Fig. 2). The chains are linked via weak hydrogen bondings of C—H···O and C—H···Cl into a three-dimensional supramolecular network.
