Comment top

The synthesis and characterization of coordination compounds with aza-macrocyclic ligands has evolved during the last years as one of the main research areas in coordination chemistry (Fry et al.,1997; Xu et al., 1997). By the end of the last century the macrocyclic polyethers (crown ethers) had became one of the most popular chemical reagents with a very wide area of applications. They are used successfully in chemistry of 'host–guest' complexes, extraction, phase transfer catalysis, organic synthesis, analytical chemistry, biology, medicine, ecology, etc. (Shishkina et al., 2007). In addition, aza-macrocyclic ligands, as well as their coordination and organometallic compounds play important roles in catalysis in the activation of small molecules, showing catalytic activity in electrochemically assisted reactions with several substrates (Canales et al., 2000).

We have investigated the title structure of macrocyclic multidentate O₂N₃ donor-type ligand (Fig. 1). The 17-membered macrocyclic ring contains two ether O and three aza N atoms. The ligand cavity for macrocyclic ring plays an important role in metal-ion selectivity (Hökelek et al.,2004; Hökelek et al., 2001).

The 17-membered macro-cyclic molecule with O₂N₃ type ring, the deviations from the least-squares plane defined by atoms O1, O2, N1, N2 and N3 are -0.661 (4)Å (O1), 0.363 (3)Å (O2), -0.352 (3)(N1) and 0.806 (3)Å (N2) and C29 shows the maximum r.m.s deviation from the plane as 1.067 (3).

The dihedral angle between the tosyl rings A(C18—C23, C24, S2) and B(C11—C16, C17, S1) is 10.6 (3)° [both nearly planar with r.m.s. deviations of 0.11 (3) Å for S1 and -0.06 (3) Å for S2, from the mean planes]. The geometry at the S atoms is distorted from the tetrahedral configuration [the largest angle is 120.3 (3)° for O3—S1—O4] and agree with the corresponding angle 120.4 (3)° in 10,11-Dibromo-3,6-ditosyl-3,6-diazabicyclo-[6.4.0]dodeca-1 (8),9,11-triene (Işik et al., 1999).

The benzene rings C(C1—C6), D(C11—C16) and E(C18—C23) are planar with the maximum r.m.s. deviation from the mean plane as 0.021 (4) Å for C13. The dihedral angles between these benzene rings are C/D = 17.8 (3)°, D/E = 10.9 (3)° and C/E = 7.4 (3)°. The conformation of the title compound's macrocyclic ring can be given by the torsion angles. The optimum values of the torsion angles in a macrocyclic ring are 180° (anti) and 60° (gauche). In the compound (I), seven torsion angles are seems to be anti and five ones as gauche (Table 1). There is no classic hydrogen bonds in (I) and van der Waals interactions are effective in the molecular packing.

N,N'-(3,3'-(methylazanediyl)bis(propane-3,1-diyl))bis(4-methyl benzenesulfonamide) (Notni et al., 2006) (1 g, 2.21 mmol) was dissolved in dry acetonitrile (50 ml) containing finely ground anhydrous Cs₂CO₃ (2.16 g, 6.63 mmol) and purged under nitrogen in a Schlenk system. This solution was stirred at 50 °C and a solution 1,2-bis(2-iodo-ethoxy) -4,5-dibromobenzene (Koçak et al., 1994) (1.27 g, 2.21 mmol) in dry acetonitrile (30 ml) was added dropwise over a period of 3 h at reflux temperature (90 °C). The reaction was monitored by TLC using hexane/ethyl acetate (1:1) and was complete in 8 days at the reflux temperature. At the end of this period the solvent was removed under reduced pressure, mixed with water (50 ml) and then extracted with chloroform (3 times 50). The combine extract was washed with water, dried over Na₂SO₄ and filtered and evaporated to dryness. The product was chromatographed on silica gel with hexane/ethyl acetate (2:3). Finally the white solid product was obtained. This product was crystallized from chloroform/hexane to yield colourless prisms of (I). This compound is soluble in chloroform, dichloromethane, dimethyl formamide. Yield: 0.65 g (%38). IR(KBr pellets): 3026 (Ar–H), 2926–2854 (Aliph.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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.
