摘要：
PbCl2.2[(SC(NH2)(2)] is an important complex for environmental chemistry. Single crystals were studied using infrared absorption, and Raman spectroscopy in low temperature conditions (10 K). Assignments of the lead complex bands were made by searching correlations and group Frequencies with separate PbCl2 and thiourea spectra in the solid state. Lattice modes separation was achieved down to 20 cm(-1) in Raman and down to 50 cm(-1) with far infrared spectroscopy. Spectral signatures of the unusual seven-coordinated lead in the complex were tentatively determined and are in accordance with structural data.
