(Received 28 June 2008; accepted 14 July 2008; online 23 July 2008)

In the title compound, [Cu(C₁₃H₂₀N₃O₂)(NO₃)]_n, the Cu^II atom is chelated by the Schiff base ligand via three N atoms and one O atom lying in an approximate square plane (r.m.s. deviation = 0.04 Å). The complex molecules are linked into a polymeric chain by bridging nitrate anions, forming axial Cu—O bonds of 2.535 (6) and 2.676 (7) Å, completing a distorted octahedral coordination geometry. The NH groups of the ligand form hydrogen bonds to the nitrate anions.

Comment top

Schiff bases have been studied as ligands for a long time due to instant and enduring popularity from their easy synthesis and versatility in complexes. They play an important role in the development of coordination chemistry as well as inorganic biochemistry, catalysis, optical materials and so on (Garnovskii et al., 1993; Huang et al., 2002). Considerable attention has been focused on the syntheses and structures of Cu^II and Ni^II complexes. The Ni^II complexes with multidentate Schiff-base ligands have aroused particular interest because Ni can exhibit several oxidation states and may provide the basis of models for active sites of biological systems. On the other hand, the main attention in the optically active Schiff-base complexes is concentrated on their catalytic abilities in stereoselective synthesis (Bhadbhade & Srinivas, 1993; Bunce et al., 1998).

Experimental top

A mixture of copper(II) nitrate hemi(pentahydrate) (1 mmol) and N-(2-hydroxy-4-methoxybenzyl)bisethylenetriamine (1 mmol) in 20 ml methanol was refluxed for two hours. The resulting solution was cooled and filtered and the filtrate was evaporated naturally at room temperature. Two day later, blue blocks were obtained with a yield of 16 %. Elemental analysis calculated: C 41.60, H 5.07, N 14.93 %; found: C 41.51, H 5.08, N 14.85 %.

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.
