“…Again, HE and LE emission of 2 and 3 could attribute to 1 IL and 3 IL transitions in the pyridine rings of the L1 ligand. In general, considering the previous studies, the dual emission is also typical for Ag (I) complexes containing N-heterocyclic ligands [24,49] as surely as pure intraligand phosphorescence [47,48] or fluorescence, [50,51] and thermally-activated delayed fluorescence. [52] Cytotoxic Activity Evaluation Compounds 3-5, 7 and 8 as well as corresponding organic ligands were studied for cytotoxic activity against a series of cancer cells, namely, immortalized human fibroblasts, HeLa, MCF7, HepG2 and A549 using the standard MTT assay procedure.…”

“…[23] These issues often lead to the lack of selectivity control over the formation of certain Ag (I) complexes or CPs. [24] As a result, the desired product is either hardly reproducible and/or it is contaminated with other Ag (I) complexes. In this context, understanding the factors that determine selectivity of the self-assembly reactions is of primary importance for directed crystal engineering of new Ag (I) -based materials with designed architecture and challenging properties.…”

“…So, in the reactions of Ag (I) salts with organic ligands, the structure of a product assembled depends not only on ligand functionality, anion nature and stoichiometry, but also on the solvent effects, concentration, and crystallization conditions . These issues often lead to the lack of selectivity control over the formation of certain Ag (I) complexes or CPs . As a result, the desired product is either hardly reproducible and/or it is contaminated with other Ag (I) complexes.…”

The potential of 2‐(alkylsulfanyl)azine ligands for crystal engineering of functional Ag(I) complexes has been firstly demonstrated. The reaction of AgNO3, AgClO4 and AgOTf with 2‐(alkylsulfanyl)pyridines, ‐pyrimidines, and ‐quinolines gives a series of new Ag(I) compounds that range from mono‐ and dinuclear complexes to chain (1D), layered (2D) and framework (3D) coordination polymers (CPs). 2‐(Alkylsulfanyl)pyridines and ‐pyrimidines, depending on the reaction conditions, are assembled either into molecular complexes or CPs, while 2‐(alkylsulfanyl)quinolines afford dinuclear complexes exclusively. The most of compounds engineered feature site‐specific interactions such as Ag···Ag, Ag···O, and Ag···S ones. The 2‐(methylsulfanyl)quinoline (2‐MeSQn) complex, [Ag2(2‐MeSQn)2(NO3)2], displays room temperature intraligand (IL) phosphorescence, while the 2‐(methylsulfanyl)pyridine‐derived CPs emit dual luminescence expressed by IL fluorescence and phosphorescence. Moreover, cytotoxic activity of the compounds synthesized has been evaluated against hTERT lung fibroblasts, HeLa, MCF7, HepG2 and A549 cancer cells.

“…At ambient temperature, the former exhibits a weak yellow luminescence (λmax = 570 nm), while the latter emits in the deep-red region (λmax = 705 nm), thus representing a rare example of a Cu(I) coordination compound showing an emission in this color range. One year later, the same group started from the same ligands to prepare the Ag(I) analogues [Ag(MTT)(NO3)]∞ and [Ag2(MTBT)2(NO3)2(MeCN)2]∞ as layered 2D CPs exhibiting Ag•••Ag interactions in the solid state [66]. The latter demonstrates dual emission behavior associated with simultaneous presence of high-energy and low-energy emission bands originated by Ag(I)-perturbed singlet and triplet π-π* and n-π* intraligand transitions, respectively.…”

The coordination chemistry of 1,10‐phenanthroline (phen) and sodium 1,3‐benzothiazole‐2‐thiolate (SBT) with selected s‐block elements has been investigated. Four metal complexes were prepared and their structures were characterized using a variety of analytical techniques including infrared, UV–visible, 1H NMR and 13C NMR spectroscopies, elemental analysis, mass spectrometry and single‐crystal X‐ray diffraction. The reactions of phen and SBT with M(X)n (M = K(I), Cs(I), Mg(II), Sr(II); X = OH−, CO3−, Cl−; n = 1, 2) in MeOH–H2O yielded one‐dimensional chains of both potassium [K2(phen)2(BT)2(H2O)4]n (1) and caesium [Cs(phen)(BS)(H2O)]n (2) (where BT = 1,3‐benzthiazole‐2‐thiolate and BS = 1,3‐benzthiazole‐2‐sulfinothiolate) and mononuclear complexes of both magnesium {[Mg(phen)(H2O)4](BT)2·phen} (3) and strontium {[Sr(phen)2(H2O)4](BT)2} (4). In these complexes, phen binds via an N,N′ chelate pocket, while the monoanonic BT− ligands either coordinate in a bidentate fashion (in the case of 1) or remain uncoordinated (in the case of 3 and 4). In complex 2, SBT ligand was oxidized in situ into a new BS ligand. The sulfinothiolate oxygen atoms in BS coordinate with caesium in a tridentate fashion. Complexes 1–4 were evaluated against urease for enzyme inhibition. The complexes displayed significant inhibition with IC50 values in the range 10.8–45.8 μM. In order to examine the structure–activity relationship, the complexes were docked at the active site of urease. Docking results clearly demonstrate the binding of each complex within the active site of the enzyme.
