Main observation and conclusion The development of bifunctional catalysts has drawn much attention in realizing efficient and feasible catalytic systems to meet the diverse demand of potential industrial applications. Design of stable and powerful bifunctional catalysts for various catalysis systems is highly desirable yet largely unmet. Here, three kinds of decavanadate‐based transition metal hybrids (DTMH) (i.e., Co‐DTMH, Ni‐DTMH and Ag‐DTMH) have been successfully synthesized through a pH tuning strategy and further characterized. Specifically, the rare MO5N six‐coordinated transition metal coordination modes have been detected in Co‐DTMH and Ni‐DTMH, while Ag atoms in Ag‐DTMH exhibited three‐ and five‐coordinated geometries with the tuning of specially selected imidazole ligands. Thus‐obtained clusters can serve as powerful bifunctional catalysts for both sulfide oxidation and C—C bond construction. Remarkably, Ag‐DTMH demonstrated excellent heterogeneous bifunctional catalytic properties in the selective oxidation of sulfides and construction of C—C bond (yields up to 99%), which enable successful recycling for three cycles with remained catalytic activities and structure stability. The newly designed decavanadate‐based transition metal hybrids with bifunctional property hold high promise in the practical applications like continuous catalysis or flow bed reactions.

“…For Ag2, two N atoms in two BPY molecules coordinate with Ag2, forming a one-dimensional chain structure (Figure c) that is different from that for Ag1. The distance between Ag1 and Ag2 is 3.50 Å, which exceeds the 3.44 Å van der Waals radius of elemental Ag . Therefore, no metal bonds are formed between the Ag atoms in Ag-PTS-BPY.…”

Photostable Ag(I)-Based Metal–Organic Framework: Synthesis, Structure, and Photocatalytic Selective Oxidation Properties

et al. 2020

For Ag(I)-based photocatalysts, the photoreduction of Ag+ to metallic Ag is an unignorable issue, which is the major reason for their instability. If electrically neutral excitons rather than electrons were produced over Ag(I)-based photocatalysts, the photoreduction of Ag+ is expected to be greatly suppressed. To check this assumption, a Ag-based metal–organic framework containing pyrene, which is in favor of exciton production, is synthesized (denoted as Ag-PTS-BPY) and the structure is solved via single-crystal X-ray diffraction. Ag-PTS-BPY is applied in the photocatalytic selective oxidation of methyl phenyl sulfide, which displays high conversion and selectivity. As expected, no metallic Ag is formed after five cycles of reaction according to the results of X-ray diffraction, Fourier transform infrared, and X-ray photoelectron spectroscopy, and the high conversion is also maintained. The participation of excitons suppresses the involvement of electrons, which are believed to be the reason for the high stability of Ag-PTS-BPY.

“…In particular, 2 0 ,6 0difluoro-2,3 0 -bipyridine complexes of iridium(III) are considered to be strong candidates as both blue triplet emitters in phosphorescent organic light-emitting diodes (PHOLEDs) and single dopants in white organic light-emitting diodes (WOLEDs) (Zaen et al, 2019;Kang et al, 2020;Lee et al, 2018). Despite these investigations, reports regarding the structures and photoluminescence properties of 2,3 0 -bipyridine-based group-11 metal complexes are scarce, and related research is limited (Li et al, 2019). Among the group-11 elements, coordination polymers of Ag I have been demonstrated to exhibit structural diversity as a result of the d 10 configuration of the metal ion (Lee et al, 2020).…”

Synthesis, crystal structure and photophysical properties of bis[2,6-difluoro-3-(pyridin-2-yl)pyridine-κN](trifluoromethanesulfonato-κO)silver(I)

In the title compound, [Ag(CF3SO3)(C10H6F2N2)2], the AgI centre adopts a highly distorted trigonal–planar coordination environment resulting from its coordination by one O atom of the trifluoromethanesulfonate anion and the pyridine N atoms of two crystallographically independent 2′,6′-difluoro-2,3′-bipyridine ligands, which display very similar conformations to one another. Pairwise Ag...O–SO2CF3 − [Ag...O = 2.8314 (14) Å] interactions and intermolecular C—H...O interactions between inversion-related units lead to the formation of an eight-membered cyclic dimer in which the silver atoms are separated by 6.2152 (3) Å. In the crystal, the dimers are linked through C—H...O hydrogen bonds, halogen...π and weak π–π stacking interactions, resulting in the formation of a three-dimensional supramolecular network. The title compound exhibits a strong and broad emission band from 400 nm to 550 nm in solution and its photoluminescence quantum efficiency is estimated to be ca 0.2, indicating that the title compound could have applications as an emitting material in organic light-emitting diodes (OLEDs).
