The cyano bridged complex of triethylenetetramine was characterized by FT-IR, Raman spectroscopy and X-ray single crystal diffraction analysis. The molecular geometry and vibrational frequencies of the complex in the ground state have been calculated by using B3LYP density functional method with LANL2DZ basis set. A good correlation was found via comparison of the experimental and theoretical vibrational frequencies of complex. The complex of the type [Zn(teta)Ni(μ-CN)(2)(CN)(2)](n) has been studied in the 4000-250cm(-1) region and assignment of all the observed bands were made. The analysis of the FT-IR and Raman spectra indicates that there are some structure spectra correlations. Copyright © 2012 Elsevier B.V. All rights reserved.
