“…This band is observed at a lower frequency in the free ligand (1430–1454 cm −1 ) and indicates an increase of the carbon-nitrogen double bond character, caused by electron delocalization toward the metal center upon coordination to the metal atoms [ 19 ]. It is found that the coordination mode of alkyl-aryl dithiocarbamate ligands with group 12 metals is bidentate by the sulfur atoms [ 20 – 22 ]. This is consistent with the crystal structure of the mercury complex.…”

Zn(II), Cd(II) and Hg(II) complexes of N-methyl-N-phenyl dithiocarbamate have been synthesized and characterized by elemental analysis and spectral studies (IR, 1H and 13C-NMR). The single crystal X-ray structure of the mercury complex revealed that the complex contains a Hg centre with a distorted tetrahedral coordination sphere in which the dinuclear Hg complex resides on a crystallographic inversion centre and each Hg atom is coordinated to four S atoms from the dithiocarbamate moiety. One dithiocarbamate ligand acts as chelating ligand while the other acts as chelating bridging ligand between two Hg atoms, resulting in a dinuclear eight-member ring. The course of the thermal degradation of the complexes has been investigated using thermogravimetric and differential thermal analyses techniques. Thermogravimetric analysis of the complexes show a single weight loss to give MS (M = Zn, Cd, Hg) indicating that they might be useful as single source precursors for the synthesis of MS nanoparticles and thin films.

“…Dithiocarbamates have interesting chemistry and applications. Pb(II) bis( N -ethyl- N -phenyl dithiocarbamate) has been used in the rubber industry as vulcanising agent [21]. The wide application of metal dithiocarbamates in materials synthesis is associated with the ability to modify the materials properties by altering the substituent group on the nitrogen atoms.…”

The synthesis of PbS nanostructures by microwave irradiation of single source precursor compounds in ethyleneglycol medium is reported. Pb(II) bis( N -ethyl- N -phenyldithiocarbamate) and Pb(II) bis( N -butyl- N -phenyldithiocarbamate) represented as complexes ( 1 ) and ( 2 ) respectively were utilised. The prepared PbS nanostructures were characterized using X-ray diffraction (XRD), Transmission electron microscopy (TEM), and absorption spectroscopy. The results showed that complex ( 1 ) can project the formation of nanorod with (111) basal plane, while ( 2 ) project the formation of nanocube with (001) basal plane. The formation of different morphologies in ethylene glycol may also be due to the selective binding to specific crystallite facets of the PbS through the hydroxyl groups of ethylene glycol. In the nanorod, the selective stabilization of the (111) face of PbS, resulted in anisotropic growth along the (100) face. The high resolution TEM images showed distinct lattice fringes which confirmed the crystallinity of the nanostructures. The band gap energies were obtained as 1.10 and 1.12 eV for the nanorods and nanocubes respectively, a significant blue shift from the bulk value (0.4 eV) which could be ascribed to quantum confinement effect. The result established the significant effect of the precursor type on the morphologies of the PbS.

“…23 Although the Cd analogue of 1 does not appear to have been structurally characterised, a Hg 2+ derivative containing the [S 2 CN(Et)Ph] anion has been reported. [26][27][28] The complex [Hg(S 2 CN{Et}Ph) 2 ] 2 (2) is not however, isostructural to the Zn material described here. 28 Complex 2 contains a metal atom in which the coordination environment is distinctly more pronounced towards square pyramidal (τ = 0.201) 17 although a similar twisted chair conformation of the [-S-Hg-S-C-] 2 ring system is clearly visible (Figure 3).…”

The title material crystallises in the triclinic crystal system in space group P-1 with Z = 2. The unit cell dimensions are a = 8.7365(6)Å, b = 10.6009(7)Å, c = 12.0210(8)Å with α = 66.343(1)°, β = 79.566(1)°, γ = 83.150(1)° and V = 1001.6(1)Å3. The final R value is 0.0307 (3905 observed reflections: I >2σ(I)). The compound is best described as a species in which each metal atom is coordinated to two dithiocarbamato groups, one of which forms a secondary bridging interaction (through a S-atom) to a second [Zn(S2CNEtPh)2] unit. Thus, the title material is in the form of a dimeric aggregate. This complex is compared to related materials which contain N-atoms within the dithiocarbamato ligand that are derived from secondary amines containing two different organic functionalities.
