Abstract top

In the title compound, [Cu(C13H20N3O2)(NO3)]n, the CuII 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 CuII and NiII complexes. The NiII 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 %.

Refinement top

H atoms bound to C atoms were placed in calculated positions with C—H = 0.93–0.97 Å and refined as riding with Uiso(H) = 1.2 or 1.5Ueq(C). The H atoms bound to N4 were also placed in calculated positions with N—H = 0.90 Å and allowed to ride with Uiso(H) = 1.2Ueq(N). Atom H1 was located in a difference Fourier map and its position was refined with the N—H distance restrained to 0.90 (1) Å and with Uiso = 0.05 Å2.

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.
