Poly[bis[chloridocopper(I)]-[mu]4-1,4-bis[1-(3-pyridylmethyl)-1H-benzimidazol-2-yl]butane]

Abstract top

The title CuI coordination polymer, [Cu2Cl2(C30H28N6)]n, was obtained by reaction of CuCl2·2H2O and 1,4-bis[1-(3-pyridylmethyl)-1H-benzimidazol-2-yl]butane. Each CuI cation is three-coordinated by a ClN2 donor set. The anion acts as a tetradentate ligand, linking CuI centres into a polymeric chain.

Comment top

As shown in Fig. 1, three are two crystallographically unique Cu ions, and each CuI ion is three-coordinated by one Cl- anion and two nitrogen atoms from two L anions. Each L anion in (I) coordinates to four CuI cations through its two imidazole N atoms and two pyridine N atoms, thus acing as a tetradentate ligand. The CuI cations are linked by L anions to form a chain along a axis. For a related compound, see Wang & Xu (2007).

Experimental top

The ligand was synthesized according to the literature (Li et al., 2007) but 4-(chloromethyl)pyridine was replaced by 3-(chloromethyl)pyridine. A mixture of CuCl2.2H2O (0.034 g, 2 mmol), H2L (0.945 g, 2 mmol), and water (8 ml) was sealed in a Teflon reactor (15 ml) and heated at 130 °C for 3 days. After the mixture had been cooled to room temperature at 10 °C.h-1, red crystals of the title compound were obtained.

Refinement top

All H-atoms bound to carbon were refined using a riding model with d(C—H) = 0.93 Å, Uiso=1.2Ueq (C) for aromatic and 0.97 Å, Uiso = 1.5Ueq (C) for CH2 atoms.

Special details top

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.
