In the title complex, [Cu(CH3COO)Cl(C16H14N4)]·H2O, the CuII ion is five-coordinated by two N atoms from a 2,2′-(ethane-1,2-diyl)di-1H-benzimidazole ligand, two O atoms from a chelating acetate ligand and one terminal monodentate Cl atom in a distorted square-pyramidal geometry. In the crystal, adjacent molecules are linked through O—H⋯Cl, N—H⋯Cl, N—H⋯O and O—H⋯O hydrogen bonds into a three-dimensional network.

1,2-Bis(2,2′-1H-benzimidazol)ethane (bbe) has been extensively used in the construction of complexes since it has multiple nitrogen donors which show strong coordination ability, see: Yang et al. (2010); van Albada et al. (2000). For the potential applications of copper complexes, see: Mirica et al. (2004); Zhang et al. (2008).

The ligand 1,2-bis(2,2'-1H-benzimidazol)ethane hydrochloride (0.1 mmol) in methanol (5 ml) was added dropwise to an aqueous solution (2 ml) of copper acetate (0.1 mmol). The resulting solution was allowed to stand at room temperature. After two weeks green crystals with good quality were obtained from the filtrate and dried in air.
H atoms are positioned geometrically and refined as riding atoms, with C-H = 0.93 (aromatic), 0.97 (CH2) and 0.96 (CH3) Å and O-H = 0.82 Å, and with Uiso(H) = 1.2 (1.5 for methyl) Ueq(C,O).
1,2-Bis(2,2'-1H-benzimidazol)ethane (bbe) has been extensively used in the construction of complexes since it has multiple nitrogen donors which show strong coordination ability (Yang et al., 2010; Albada et al., 2000). In addition, copper complexes have received much more attention owing to their potential applications in catalysis, magnetism, electrical conductivity, optical materials and so on. (Mirica et al., 2004; Zhang et al., 2008). In this work, through the reaction of 1,2-bis(2,2'-1H-benzimidazol)ethane hydrochloride with copper acetate at room temperature, we obtained the title complex [Cu(bbe) (C H3C O O) (Cl)]H2O, which is reported here.
In the title complex, each CuII ion is five coordinated by two oxygen atoms from a chelating acetate ligand, two nitrogen atoms from a bbe ligand and one terminal monodentate Cl atom. Atoms N1, N3, O1, O2 and Cu1 are nearly co-planar (the mean deviation from plane is 0.1042 Å). Cl1 atom is located in the apical position. So the local environment around the central CuII ion can be best described as a distorted square pyramidal geometry.(Fig.1). In addition, there are four kinds of hydrogen bonds in the solid state. (a) O—H···Cl hydrogen bond between uncoordinated water and Cl atom, (b) N—H···Cl hydrogen bond between bbe ligand and Cl atom, (c) N—H···O hydrogen bond between bbe ligand and uncoordinated water, (d) O—H···O hydrogen bond between uncoordinated water and acetate group. [Cu(bbe) (C H3C O O) (Cl)] H2O units are linked through these hydrogen bonds resulting in a three-dimensional packing structure in solid state.

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. |

1,2-Bis(2,2'-1H-benzimidazol)ethane (bbe) has been extensively used in the construction of complexes since it has multiple nitrogen donors which show strong coordination ability (Yang et al., 2010; Albada et al., 2000). In addition, copper complexes have received much more attention owing to their potential applications in catalysis, magnetism, electrical conductivity, optical materials and so on. (Mirica et al., 2004; Zhang et al., 2008). In this work, through the reaction of 1,2-bis(2,2'-1H-benzimidazol)ethane hydrochloride with copper acetate at room temperature, we obtained the title complex [Cu(bbe) (C H3C O O) (Cl)]H2O, which is reported here.
In the title complex, each CuII ion is five coordinated by two oxygen atoms from a chelating acetate ligand, two nitrogen atoms from a bbe ligand and one terminal monodentate Cl atom. Atoms N1, N3, O1, O2 and Cu1 are nearly co-planar (the mean deviation from plane is 0.1042 Å). Cl1 atom is located in the apical position. So the local environment around the central CuII ion can be best described as a distorted square pyramidal geometry.(Fig.1). In addition, there are four kinds of hydrogen bonds in the solid state. (a) O—H···Cl hydrogen bond between uncoordinated water and Cl atom, (b) N—H···Cl hydrogen bond between bbe ligand and Cl atom, (c) N—H···O hydrogen bond between bbe ligand and uncoordinated water, (d) O—H···O hydrogen bond between uncoordinated water and acetate group. [Cu(bbe) (C H3C O O) (Cl)] H2O units are linked through these hydrogen bonds resulting in a three-dimensional packing structure in solid state.
