摘要：

The FT-Raman spectra of Se(tu)(2)Cl-2 and Se(tu)(2)Br-2 complexes are reported for the first time. The important modifications observed in the Raman active modes of thiourea molecules demonstrate a very strong interaction between the Se(II) ion and the sulfur atom of the ligand. As a result of this coordination, and through a "resonance-assisted" mechanism, an intense hydrogen-bonded network is present in the crystal structure of the complexes with notable vibrational effects.
