Structures and vibrational spectra of the N-benzoyl N′-dialkylthiourea derivative and their complexes with Hg(II)

The complex Hg (MTCB)2 (MTCB=N-(morpholinothiocarbonyl) benzamide) and Hg (PTCB)2 (PTCB=N-(piperidylthiocarbonyl) benzamide) have been synthesized and characterized by elemental analysis, FT-IR, FT-Raman spectra and NMR methods. The complex, Hg (MTCB)2, crystallizes in the triclinic space group View the MathML sourceP1¯, with Z=2. Unit cell parameters, a=10.3621(11) Å, b=11.5738(11) Å, c=12.7722(7) Å, α=64.493(8)°, β=66.132(8)°, γ=85.811(11)°, V=1254.7(2) Å3. The FT-Infrared and FT-Raman spectra were used in study of the structures of MTCB, PTCB and their complexes with mercury cation, which were agreement with the result of X-ray diffraction.
