Ternary copper-incorporated group 8 (Ru or Fe) carbonyl chalcogenide complexes and polymers: From syntheses to applications

Structure–Property Relationships of Inorganic–Organic Hybrid Semiconducting Se–Fe–Cu–CO Polymers

“…On the basis of the literature search, the introduction of main-group metal carbonyl clusters as either building nodes or bridging ligands into coordination polymers is usually achieved by solution-based reactions. , Solid-state mechanochemical approaches were recently reported to provide highly efficient synthetic routes to many different types of coordination polymers. , In 2017, a series of dipyridyl-linked 1D and 2D Te–Fe–Cu–CO-based semiconducting polymers were quantitatively synthesized by our group via liquid-assisted grinding (LAG) from the predesigned cluster [TeFe 3 (CO) 9 Cu 2 (MeCN) 2 ] as the building node with dipyridyl linkers . Prompted by this efficient and clean synthetic method, we investigated the issue of whether SeFe 3 (CO) 9 –dipyridyl hybrid Cu polymers could be directly obtained by using Cu­(I) ions in combination with the redox-active intact cluster [SeFe 3 (CO) 9 ] 2– and dipyridyls via LAG reactions.…”

“…In addition, IR spectra revealed that the CO stretching frequencies of the resulting polymers were significantly blue-shifted in comparison to those of 1 (Table S1), supporting the success of the coordination of 1 into Cu atoms of the polymeric frameworks. According to a literature search, the three-component mechanochemical synthetic route adopted for preparing metal carbonyl cluster-incorporated polymers has never been reported previously, even though solution-based one-pot approaches to such polymers have been developed. , This study provides the first examples of a facile and direct three-component mechanochemical synthesis, leading to the selective polymerization of metal carbonyl clusters along with a Cu­(I) node and organic ligands.…”

“…During the last few decades, coordination polymers have received a great amount of attention owing to their versatile topologies, special properties, and wide variety of applications. , In this research area, either the judicious choice of multidentate organic ligands or the design of sophisticated metal complexes or clusters as secondary building units has proven to be feasible methods for the construction of unusual coordination polymers possessing intriguing architecture and promising properties. Nevertheless, metal carbonyl cluster-based polymers remained scarce , but have attracted considerable attention in the field of metal carbonyl cluster chemistry because metal carbonyl clusters, in conjunction with existing strong π-acceptor carbonyl ligands, usually have special intrinsic physical/chemical properties, − ,, which could modulate the functionality of the resulting polymers for material science.…”

“…The incorporation of electronegative main-group elements into metal carbonyl clusters could further fine-tune their electronic properties, providing multifunctional synthons that could coordinate with the electropositive metals in the presence/absence of organic ligands, giving rise to different types of cluster-based polymers . Apart from using main-group-incorporated metal carbonyl clusters as repeating nodes, the idea of such clusters serving as inorganic ligands has been limited to only a few examples, such as EFe 3 -based one-dimensional (1D) zigzag chains, [{Et 4 N}­{TeFe 3 (CO) 9 Cu}] n and [SFe 3 (CO) 9 Cu 2 (dppe)­(MeCN) 2 ] n (dppe = bis­(diphenylphosphino)­ethane), as well as P 2 Mo 2 -based 1D, 2D, and 3D polymers − by employing [EFe 3 (CO) 9 ] 2– (E = Te, S) or [{CpMo­(CO) 2 } 2 P 2 ] as inorganic or organometallic ligands to connect M­(I) (M = Cu, Ag) nodes.…”

Introductory Chapter: Chalcogen Chemistry - The Footprint into New Materials Development

“…A great variety of technological applications are now found for the many compounds of the elements of chalcogens [28][29][30][31][32][33][34]. This textbook emphasizes on this shift from not only fundamental chalcogen chemistry but also on the new shift to new chalcogen materials synthesis, characterization, and testing.…”
