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

A new ligand containing the long aliphatic hydrocarbon chain, dipyridylstea rylamine (dps) and its copper(II) complex, Cu(dps)(NO3)(2) have been prepar ed. The copper complex was characterized structurally and spectroscopically . The XRD crystal structure of the copper complex reveals that copper is oc tahedrally coordinated by dps and two nitrate ligands. The nitrate groups l igate asymmetrically to the copper. Crystal data are P1bar, a=8.249(2), b=1 0.416(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 An gstrom, mu =0.689 mm(-1), T=293(2) K, R=0.0560 for 3529 reflections. The dp s and the copper complex are stable in the air and the copper complex exhib its features of typical of other copper(ll) complexes containing dipyridyla mine-based ligand.
