Comment top

Some benzimidazole derivatives can be used as building blocks in the synthesis of model complexes (Ogawa et al., 1998; Liu et al., 2002; Blackburn et al., 1989; Plengea et al., 2003). The hexadentate polyfunctional benzimidazole ligand EDTB [EDTB is N,N,N',N'-tetrakis(2-benzimidazolylmethyl)-1,2-ethanediamine] has attracted considerable attention in recent years, and a series of compounds containing this ligand have been reported. Among these, [Mn(EDTB)(Ac)](Ac)·C₂H₅OH (Liao et al., 2001) shows SOD-like activity, while Cu(EDTB)(NO₃)₂·C₂H₅OH (Chen et al., 2004) exhibits catecholase-like activity. As an extension of this work, we have synthesized the title compound, (I), and report its crystal structure here.

The asymmetric unit of (I) consists of an [Ni(EDTB)]²⁺ cation, two NO₃⁻ anions and a methanol molecule (Fig. 1). Selected bond lengths and angles are listed in Table 1. The Ni^II ion is six-coordinated by four benzimidazole and two amino N atoms, forming a distorted octahedral geometry. The equatorial plane is made up by the N atoms of two benzimidazole groups [Ni—N1 = 2.046 (2) Å and Ni—N7 = 2.095 (2) Å] and two amino N atoms [Ni—N3 = 2.186 (2) Å and Ni—N6 = 2.137 (2) Å], while the axial positions are occupied the N atoms of the other two benzimidazole groups [Ni—N4 = 2.094 (2) Å and Ni—N9 = 2.098 (2) Å]. The N4—Ni1—N9 angle is 171.40 (8)°, and the Ni atom is displaced by 0.023 (5) Å from the equatorial plane. The crystal packing is stabilized by intermolecular N—H···O, N—H···N and O—H···O hydrogen bonds (Table 2).

Experimental top

EDTB was prepared as described previously by Gomez-Romero et al. (1990). EDTB (1 mmol) was dissolved in hot methanol (15 ml) and a solution of Ni(NO₃)₂·6H₂O (1 mmol) in water (10 ml) was added dropwise. The mixture was filtered after continuous stirring for 3 h. Violet single crystals of (I) suitable for X-ray analysis were obtained by slow evaporation of the solution at room temperature over a week. Analysis calculated for C₃₅H₃₆N₁₂NiO₇: C 56.55, H 4.34, N 22.61%; found: C 57.46,H 4.52,N 23.02%.

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.
