In the title compound, [Zn(C21H25N3O2)], the ZnII atom is five-coordinate from three N donor atoms and two O donor atoms of the dianion ligand in a distorted trigonal–bipyramidal arrangement. Three methyl­ene groups of the ligand are disordered over two orientations in a 0.555 (6):0.445 (6) ratio.

Comment top

Schiff-base ligands are able to coordinate to metal ions through their imine nitrogen atoms and another group, usually linked to the aldehyde moiety. They have long played a key role in coordination chemistry (e.g. Niu et al., 2005; Herzfeld & Nagy, 1999). We now report the synthesis and structure of the title compound, (I).

The ZnII center in (I) is five-coordinate with three N donor atoms and two O donor atoms of salicylaldehyde-N,N-bis-(3-aminopropyl)methylamine, and forms a distorted trigonal bipyramidal arrangement (Table 1, Fig. 1) with the O atoms in the equatorial sites. The dihedral angle between the aromatic rings is 72.23 (19)°.

Experimental top

1 mmol of ZnII acetate was added to a solution of salicylaldehyde-N,N-bis(3-aminopropyl)methylamine (1 mmol) in 10 ml of ethanol. The mixture was continuously stirred for 3 h at refluxing temperature, evaporating some ethanol, then the product was collected by filtration, yield 68%. IR (KBr disk): 1614 (m) (C=N). Colourless blocks of (I) were grown by slow evaporation of an ethanol solution.

Refinement top

Three methylene groups (C1, C4, C7) of the ligand are disordered over two positions in a 0.555 (6):0.445 (6) ratio (sum of occupancies constrained to unity). The positions of all H atoms were fixed geometrically (C—H = 0.93–0.97 Å) and refined as riding with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C).

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.
