“…Figure 5(a) shows the FT-IR spectra of HDA and the water-soluble Cu nanoparticles in the range 400-4,000 cm −1 . For pure HDA, as expected, the hydroxyl functionality produces [28], and the absorption peak at 1,614 cm −1 is attributed to the O-H bending vibration. The absorption peaks at 2,877 and 2,947 cm −1 are attributed to the symmetric and asymmetric stretching vibrations of C-H, respectively.…”

Efficient and sustainable use of water-based lubricants is essential for energy efficiency. Therefore, the use of water-lubricated mechanical systems instead of conventional oil lubricants is extremely attractive from the viewpoint of resource conservation. In this study, water-soluble Cu nanoparticles of size approximately 3 nm were prepared at room temperature (around 25 °C) via in-situ surface modification. The tribological behavior of the as-synthesized Cu nanoparticles as an additive in distilled water was evaluated using a universal micro-tribotester. The results show that the as-synthesized Cu nanoparticles, as a water-based lubricant additive, can significantly improve the tribological properties of distilled water. In particular, the lowest friction coefficient of 0.06 was obtained via lubrication with a concentration of 0.6 wt% of Cu nanoparticles in distilled water, which is a reduction of 80.6% compared with that obtained via lubrication with distilled water alone. It is considered that some Cu nanoparticles entered the contact area of the friction pairs to form a complex lubricating film and prevent direct contact of the friction pairs. Furthermore, some Cu nanoparticles in the solution accelerate the heat transfer process, which also results in good tribological properties.

“…Finally, the 31 P{ 1 H} NMR showed singlets a few ppm downfield for the copper(I) compounds, and upfield for the silver(I) compounds. The appearance of singlets is consistent with rapid exchange of the phosphane ligands in solution [30]. Full structure determination for two species, namely 1.CH2Cl2 and 4 were afforded by Xray crystallography.…”

“…0.83, the coordination geometry is less distorted from the ideal tetrahedral geometry compared with 1 in 1.CH2Cl2. There are three literature precedents for (Ph3P)2Ag(S2CNR2) [30,37], including a very recently reported structure for 4 but, as its dichloromethane solvate [30]; see Table 2 for salient geometric data. A comparison of the key geometric parameters for 4 and 4.CH2Cl2 [30] clearly confirms the flexibility in this class of molecule as, for example, the Ag-S bond lengths in 4.CH2Cl2 differ by only 0.02 Å cf.…”

Keywords: Copper(I) / silver(I) / dithiocarbamate / crystal structure analysis / X-ray diffraction Abstract.The crystal and molecular structures of (Ph3P)2M[S2CN(Me)CH2CH2OH], M = Cu, isolated as a 1:1 dichloromethane solvate (1.CH2Cl2), and M = Ag (4) show the central metal atom to be coordinated by a symmetrically (1.CH2Cl2) and asymmetrically chelating (4) dithiocarbamate ligand. The distorted tetrahedral geometries are completed by two PPh3 ligands. The presence of hydroxyl-O-H … S(dithiocarbamate) hydrogen bonds leads to centrosymmetric dimeric aggregates in each crystal structure. In the molecular packing of 1.CH2Cl2, channels comprising 1 are formed via aryl-C-H … O interactions with the solvent molecules associated with the walls of the channels via methylene-C-H … S, π(aryl) interactions. For 4, the dimeric aggregates are connected via a network of aryl-C-H … π(aryl) interactions. Preliminary screening for antimicrobial activity was conducted. The compounds were only potent against Gram-positive bacteria. Some further selectivity in activity was noted. Most notably, all compounds were active against methicillin resistant Staphylococcus aureus.

“…Dithiocarbamates have attracted attention as readily accessible and structurally changeable ligands for transition metal ions and have even found manifold practical use [6][7][8].
