Nitrato[N,N,N′,N′-tetra­kis(1H-benzimid­azol-2-ylmeth­yl)ethane-1,2-diamine]­calcium(II) nitrate methanol trisolvate

Abstract

In the title compound, [Ca(NO₃)(C₃₄H₃₂N₁₀)]NO₃·3CH₄O, the Ca^II ion is coordinated by six N atoms of the EDTB ligand {EDTB is N,N,N′,N′-tetra­kis[(2-benzimidazol­yl)meth­yl]-1,2-ethanediamine} and two O atoms from the nitrate ligand, to form a distorted dodeca­hedral geometry. The crystal packing is stabilized by inter­molecular N—H⋯O, N—H⋯N and O—H⋯O hydrogen bonds, which link the constituent units into a three-dimensional network. The uncoordinated nitrate anion is disordered over two sites, with fixed occupancies of 0.77 and 0.23.

Comment

Benzimidazole containing ligands and their metal complexes have been reported (Chen et al., 2004; Liao et al., 2001; Pei et al., 2007). In continuation of our work on these types of ligands, we report here the crystal structure of the title compound, [Ca(EDTB)(NO₃)]⁺.NO₃^-.3CH₃OH (EDTB is N,N,N',N'-Tetrakis-[(2-benzimidazolyl)methyl] -1,2-ethanediamine).

The asymmetric unit consists of one [Ca(EDTB)(NO₃)]⁺ cationic unit, one uncoordinated nitrate anion and three methanol solvent molecules (Fig. 1). The structure of the monocation shows an eight-coordinated geometry with Ca^II ion at the centre of a distorted dodecahedral environment (Table 1). The Ca^II ion is coordinated by four benzimidazole (bzim) N atoms (N3,N5,N7 and N9) and two amine N atoms (N1 and N2) from the EDTB ligand, and two O atoms (O1/O2) from the coordinated nitrate ion.

The coordination cations, uncoordinated nitrate anions and free methanol molecules are interlinked into a three-dimensional network by a combination of six N—H···O, two O—H···O and three C—H···O hydrogen bonds (Table 2 and Fig. 2).

Experimental

N,N,N',N'-Tetrakis-[(2-benzimidazolyl)methyl] -1,2-ethanediamine (EDTB) ligand was synthesized according to the literature method (Hendriks et al., 1982). EDTB (0.58 g, 1.0 mmol) in hot methanol (20 ml) was added slowly to a solution of Ca(NO₃)₂.4H₂O (0.236 g, 1.0 mmol) in methanol (10 ml) and the mixture was stirred for 1 h. After filtration, the solution was allowed to stand at room temperature. Block-shaped pale red crystals suitable for X-ray analysis were obtained after several days in 45% yield.

Refinement

The nitrate anion is disordered over two sites. The site occupancies were initially refined to 0.77 (1) and 0.23 (1) for the major and minor components, respectively, and later fixed. In both disorder components, the N—O distances were restrained to 1.38 (1) Å and the O···O distances were restrained to be equal. C-bound H atoms were positioned geometrically (C—H = 0.93–0.97 Å) and were refined as riding with U_iso(H) = 1.2–1.5U_eq(C). O– and N-bound H atoms were first located in a difference map and then constrained to be at their ideal positions (O—H = 0.82 Å and N—H = 0.86 Å) with U_iso values set at 1.2U_eq(N) and 1.5U_eq(O).

Special details

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.
