The ethanol solution (20 ml) of N,N'-bis[(3,4-methylenedioxybenzyl)-2,2'-diaminodiethyl]amine (1.86 g, 5 mmol) was mixed with the ethanol solution (30 ml) of zinc chloride (1.36 g, 10 mmol), the mixture was stirred for 4 h at 340 K. The crude solid obtained was filtered off and washed successively with ethanol. Single crystals of the title compound were obtained by slow evaporation of a DMF-chloroform-ethanol (1:5:10) solution of the crude product over a period of three weeks.
H atoms were placed in calculated positions with C—H = 0.93 (aromatic), 0.97 (methylene), N—H = 0.91 and O—H = 0.82 Å, and refined in riding mode with Uiso(H) = 1.2Ueq(carrier). Site occupancy factor for O5 atom was refined and converged to 0.529 (3), in the final cycles of refinement it was fixed as 0.5. The crystal quality is poor, the accuracy of the structure determination is low. The highest peak in difference Fourier map is 2.1 Å apart from C18 atom.

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. |

We have reported recently the crystyl structure of a ZnII complex (Han et al., 2006). As part of our study of the ZnII complexes with the diamine derives, we report here the crystal structure of a new ZnII complex.
The title complex is a mononuclear compound, and the central zinc ion is five-coordinated by two Cl- ions and three N atoms from a tridentate ligand N,N'-bis[(3,4-methylenedioxybenzyl)-2,2'-diaminodiethyl]amine (Fig. 1). The tridentate ligand chelates to the ZnII ion in a meridional configuration. The coordination geometry around the ZnII ion is a distorted trigonal bipyramid. The Zn—Cl and Zn—N bond lengths (Table 1) are slightly longer than those found in the related ZnII complex (Han et al., 2006).
The extensive hydrogen bonding network helps to stabilize the crystal structure (Table. 2).
