Vibrational spectroscopic study of the semiorganic nonlinear optical crystal bis(thiourea)cadmium chloride

Abstract

Polarized Raman and infrared spectra of bis(thiourea)cadmium chloride, a novel semiorganic nonlinear optical crystal, were recorded to determine the symmetries of molecular vibrations. The observed Raman and infrared bands are assigned to molecular vibrations of thiourea, cadmium-sulphur and cadmium-chloride bonds. The vibrational spectra are interpreted in the light of crystal structure data.

Influence of solvent on the morphology and photocatalytic properties of ZnS decorated CeO2 nanoparticles

“…S1 51 agreed reasonably well with thiourea vibrations, 60 especially when comparing with Zn[CS(NH 2 ) 2 ] 3 2À complexes. 61 Additionally, bands near 2915 and 3310 cm À1 that overlapped the hydroxyl broad absorption band were a close fit to bands corresponding to coordinated thiourea.…”

Metal complexes of the nanosized ligand N-benzoyl-N′-(p-amino phenyl) thiourea: Synthesis, characterization, antimicrobial activity and the metal uptake capacity of its ligating resin

“…For instance, 3-monosubstituted aroylthioureas [19][20][21], the carbonyl group and the proton on the N3 engage in a strong hydrogen bond interaction and united into a planar six-membered ring structure forming an "S" shaped conformation of the C=O and C=S groups [22]. Reactions of aroylthiourea with d 10 metal (II) ions such as Zn (II), Cd (II), and Hg (II) have received renewed attention due to their non-linear optical properties [23,24].…”

Synthesis and Use of [Cd(Detu)2(OOCCH3)2]·H2O as Single Molecule Precursor for Cds Nanoparticles

“…Substituted thiourea shows more diverse coordination chemistry because of its conformational isomerism, steric effect, and the presence of donor sites on the substituted groups and intramolecular interactions [1–9]. Their chemistry has attracted attention due to various applications in separation of metal ions and as antimicrobial agents [2–8].…”

“…Several studies have been done to understand the coordination chemistry of this type of ligand and its biological activities [7–10] and recently the use of the d 10 metal complexes as precursors for metal sulfide nanoparticles [11–14]. Group 12 coordination compounds of thiourea have received attention in recent years for their nonlinear optical properties [9, 10] and their use as single source precursors for the preparation of semiconducting materials based on metal sulfide (MS) through thermal decomposition of the corresponding complexes [2, 11–15]. In this study, the synthesis, characterization, and thermal and single crystal X-ray studies of Cd(II) complex of diethylthiourea are presented.…”
