Synthesis, crystal structure and spectroscopic characterization of a copper(II) complex coordinated by 2,2 '-dipyridylstearylamine

Abstract

A new ligand containing the long aliphatic hydrocarbon chain, dipyridylstearylamine (dps) and its copper(II) complex, Cu(dps)(NO3)(2) have been prepared. The copper complex was characterized structurally and spectroscopically. The XRD crystal structure of the copper complex reveals that copper is octahedrally coordinated by dps and two nitrate ligands. The nitrate groups ligate asymmetrically to the copper. Crystal data are P1bar, a=8.249(2), b=10.416(3), c=20.915(4) Angstrom, alpha =86.54(2), beta =84.026(2), gamma =72.32(2)degrees V=1702.7(7) Angstrom (3), Z=2, lambda (Mo K alpha)=0.71073 Angstrom, mu =0.689 mm(-1), T=293(2) K, R=0.0560 for 3529 reflections. The dps and the copper complex are stable in the air and the copper complex exhibits features of typical of other copper(ll) complexes containing dipyridylamine-based ligand.
