“…The residual stretching vibration peak of S−H at 2521 cm −1 and absence stretching vibration peak of S−H at 2534 cm −1 in [Ag 2 BTT] n suggest the existence of ‐SH and coordination of ‐SH with Ag ions, respectively [25] . For [Ag 2 BDT] n , the Raman spectra of BDT and [Ag 2 BDT] n in the range of 50–400 cm −1 are shown in Figure S6, the peak at 96 cm −1 is ascribed to the stretching vibration peak of Ag−Ag [26,27] . The Raman peak of the benzene ring appears at 1566 cm −1 (Figure S7).…”

Coordination polymers (CPs) display great potential for the development of highly active photocatalysts. Herein, we report the fabrication of a highly crystalline CP, [Ag2BTT]n (BTT=benzene‐1,2,4,5‐tetrathiol). The crystal structure of [Ag2BTT]n was resolved and its performance for photocatalytic oxidation of thioanisole was explored. [Ag2BTT]n is highly active and selective for the photo‐oxidation of sulfides to sulfoxides under mild conditions, that is, in air, at room temperature and in the absence of a sacrificial reagent, co‐catalyst or redox mediator.

Nickel(II) complex with sarcosine [Ni(sar) 2 (H 2 O) 2 ] (1) has been obtained as a reaction product of a system: Ni(II)Cl 2 -1-methylhydantoin. Basic hydrolysis of the organic substrate leads to in situ formation of sarcosine ligand, which coordinates to the metal ion. The isolated complex has been characterized by means of single crystal X-ray diffraction and spectroscopic studies (IR, Raman, and NIR-UV-Vis) supported with DFT calculations. Single crystal X-ray diffraction revealed that the nickel environment in [NiN 2 O 4 ] chromophore exhibited the geometry of a tetragonally elongated octahedron. Hydrogen bonds create two chain patterns which propagate along the main crystallographic directions a and b. It leads to the formation of a 2D network. Electronic spectra analysis showed that the nickel surroundings can be described as pseudooctahedral in solution and tetragonal in the solid state. Based on the calculated 10Dq parameter (10,990 cm -1 ), sarcosine ligand was located in the spectrochemical series close to ammonia. Comprehensive studies of the molecular structure and vibrational spectra of the title complex have been performed using UPBE0, unrestricted density functional method. The clear-cut assignment of the bands in FT-IR and Raman spectra of studied complex has been made on the basis of the calculated potential energy distribution. The Ni-L(sarcosine) stretching vibrations were assigned in Raman spectrum to the medium intensity band at 442 cm -1 .

“…Silver thiolate oligomers have a marked tendency to establish coordinative Ag−S bonds and Ag⋅⋅⋅Ag, argentophilic contacts [26] . While the nature and strength of the analogous aurophilic (Au⋅⋅⋅Au) interactions [27] have been extensively studied and their importance in the self‐assembly of gold‐based molecular and cluster materials has been proved, [28–34] the strength and nature of argentophilic interactions is much less explored [26,35–37] . In general, the occurrence of argentophilic interactions is mostly proposed over the base of van der Waals distances [38–41] .…”

Structural Diversity and Argentophilic Interactions in Small Phosphine Silver(I) Thiolate Clusters

et al. 2021

Silver(I) coordination compounds display an interesting geometrical diversity, the possibility of having distinct coordination numbers (typically from 2 to 4) and the capability of forming argentophilic (Ag⋅⋅⋅Ag) interactions. These properties complicate the accurate prediction of structures of silver complexes under certain experimental conditions. In this work, we show how subtle modifications in thiolate and phosphine ligands exert important effects on the nuclearity and geometry of phosphine caped clusters [Ag(SR)]n (n=4, 6 and 8). We rationalize these effects in terms of the electronic environment of silver centers by analyzing the electronic density of the single‐crystal X‐ray structures via the Quantum Theory of Atoms in Molecules (QTAIM) and the Non‐Covalent Interaction (NCI)‐Index. Furthermore, we characterized attractive and repulsive argentophilic contacts by means of the Interacting Quantum Atoms (IQA) energy partition. Our results provide insights on the effects of ancillary ligands in controlling the structure of silver‐thiolate clusters. Such control is relevant towards a bottom‐up approach to the atomic precise construction of higher nuclearity clusters.
