“…The Cu1-N3 and Cu1-N6 distances are in the range of comparable Cu(I) triazole complexes. 72,73 The copper atom and the two gold atoms form a triangle with interior angles of 54.52(4)°(Cu1-Au1-Au2), 58.10(4)°( Cu1-Au2-Au1) and 67.37(4)°(Au1-Cu1-Au2). The intermetallic distances are close to comparable complexes showing heterometallophilic interactions between Au and Cu.…”

“…3100 cm À1 and bands in the 1100-1300 cm À1 range can be related to n(C-H) and n(C-N) or n(N-N) of triazole moieties of L 1 , respectively. 29 TGA curves were performed to gauge the thermal stability of compounds 1-3. The result is consistent with the crystallographic observations for 1-3.…”

In this work the multi-dentate 4-amino-benzene-1,2,4-triazole (L 1 ) ligand is used. A series of novel clusterbased micro-porous luminescent cadmium(II) frameworks, namely [Cd 3 5H 2 O} n (3) have been isolated under hydrothermal conditions. 1 presents a 4-connected (4,4) topology using trinuclear Cd(II) clusters as basic nodes. For 1, two bridging m 2 -Cl À anions and two bridging m 3 -L 1 ligands connect three neighboring Cd II ions forming trinuclear Cd 3 clusters. Each Cd 3 cluster links four neighboring Cd 3 clusters forming a 2D (two-dimensional) neutral micro-porous framework. 1D rhombic channels with dimensions of 7.594(2) Å Â 21.250(6) Å can be observed along the c-axis. 2 presents a rare I 1 O 3 hybrid type micro-porous framework. In 2 these bridging m 3 -L 1 ligands link central Cd II ions forming a 3D Cd-L 1 organic connectivity. Two kinds of 1D Cd-Br-Cd inorganic connectivities further consolidate the 3D Cd-L 1 organic connectivity, which ultimately forms a rare I 1 O 3 type hybrid framework. 3 presents a novel 3D cluster-based micro-porous cation framework containing 1D channels, in which guest CdI 4 2À anions and water molecules are located. Topological analysis indicates that 3 presents a novel 4-connected dmp topology using binuclear Cd 2 I 2 clusters as basic nodes. PXRD, TGA and Gas absorption experiments for 1-3 have also been carried out. Solid state photo-luminescent spectra of 1-3 have been determined indicating strong emission bands. For 1 selective photo-luminescent quenching for NO 2 À anions can be observed. The result also reveals that L 1 can adopt various different coordinated modes and flexible spatial distortion dihedral angles (between aromatic benzene and triazole rings), which has great potential in the construction of these novel cluster-based micro-porous coordination frameworks.

“…( Figure 1 ). Because of their excellent chemical stability against oxidation, reduction, and hydrolysis, they have a wide range of medical applications [ 41 , 42 , 43 , 44 ]. Due to their wide range of biological significance, triazoles have been recognized as prominent pharmacophores for several commercial drugs ( Figure 2 ) [ 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 ].…”

Molecular hybridization represents a new approach in drug discovery in which specific chromophores are strategically combined to create novel drugs with enhanced therapeutic effects. This innovative strategy leverages the strengths of individual chromophores to address complex biological challenges, synergize beneficial properties, optimize pharmacokinetics, and overcome limitations associated with single-agent therapies. Coumarins are documented to possess several bioactivities and have therefore been targeted for combination with other active moieties to create molecular hybrids. This review summarizes recent (2013–2023) trends in the synthesis of coumarins, as well as coumarin–chalcone and coumarin–triazole molecular hybrids. To cover the wide aspects of this area, we have included differently substituted coumarins, chalcones, 1,2,3– and 1,2,4–triazoles in this review and considered the point of fusion/attachment with coumarin to show the diversity of these hybrids. The reported syntheses mainly relied on well-established chemistry without the need for strict reaction conditions and usually produced high yields. Additionally, we discussed the bioactivities of the reported compounds, including antioxidative, antimicrobial, anticancer, antidiabetic, and anti-cholinesterase activities and commented on their IC50 where possible. Promising bioactivity results have been obtained so far. It is noted that mechanistic studies are infrequently found in the published work, which was also mentioned in this review to give the reader a better understanding. This review aims to provide valuable information to enable further developments in this field.
