“…The conformation m -ETTC displays within a MOF will be highly dependent on the metal used in the inorganic unit as this will dictate the connectivity of the secondary building unit (SBU). Cadmium(II) is an excellent metal for the construction of LMOFs as it possesses a d 10 electron configuration, is relatively inexpensive, and has been shown to form a wide array of structures and topologies. , The SBUs of Cd-based MOFs have a high degree of variability and include the dinuclear clusters, − dinuclear paddle wheels, − trinuclear clusters, 1-dimensional chains, , or single cadmium(II) ions. − Though less common, cadmium has also been shown to form other SBUs such as tetranuclear − and pentanuclear clusters . Tetraphenylethene-based linkers have been used to construct cadmium-based LMOFs .…”

Two cadmium coordination polymers, WSU-30 and WSU-31, were synthesized through solvothermal methods by using the low-symmetry TPE-based linker m-H 4 ETTC. The m-H 4 ETTC linker and both coordination polymers were fully characterized by using single-crystal X-ray diffraction, infrared spectroscopy, and photoluminescent emission spectroscopy. Structural analysis of WSU-30 and WSU-31 showed that each compound contains previously unknown tetranuclear cadmium(II) secondary building units. The topological analysis revealed that the 4,8-connected net of WSU-30 contains the underlying topology, alb-4,8-P21/c-1, while the mixed linker WSU-31 possesses a 3,10-connected net known as 3,10T31 topology. If the m-ETTC linker is considered as two 3connected nodes, WSU-30 possesses a very rare 3,3,8-connected 3,3,8T25 topology, and WSU-31 possesses a previously unknown 3,12-connected net, named 3,12T61.

Three Htrz‐based metal complexes, [Cd(trz)(CH3OH)(nb)]n (1), [Cd(Htrz)(H2O)(nb)2]n (2), and {[Mn(Htrz)2(H2O)4]·2nb} (3) (Htrz = 1,2,4‐triazole, Hnb = 4‐nitrobenzoic acid), have been synthesized by diffusion or solvent evaporation method and structurally characterized by single crystal X‐ray crystallography, elemental analysis, IR and fluorescence spectroscopy, and TG‐DTA. Structural determinations revealed that complex 1 has a two‐dimensional (2D) layer structure constructed by tridentate μN1,N2,N4‐bridging trz anions and CdII ions. Complex 2 presents a 1D polymeric chain structure bridged by bidentate μN1,N4‐bridging Htrz molecule and CdII ions, whereas compound 3 is a supramolecular assembly containing a mononuclear [Mn(Htrz)2(H2O)4]2+ dication and two free nb anions for charge compensation. Thus, the structural diversity of the three complexes is significantly governed by the coordination modes of the neutral/deprontated Htrz ligand, rather than the terminal/lattice nb anion. Additionally, the thermal stability of the complexes is observed to be dependent on the polymeric or discrete structure nature. At room temperature, the three solid complexes show Htrz‐based intraligand fluorescent emission.

Two bis‐triazole‐bis‐amide‐based copper(II) coordination polymers, [Cu4(μ3‐OH)2(dtb)(DNBA)6(H2O)2]·2H2O (1) and Cu(dtb)(DNBA)2 (2) [dtb = N,N′‐bis(4H‐1, 2, 4‐triazole)butanamide and HDNBA = 3, 5‐dinitrobenzoic acid], were synthesized and structurally characterized. Polymer 1 shows a one‐dimensional (1D) chain based on tetranuclear CuII cluster and the dtb ligands, whereas polymer 2 exhibits a 1D chain constructed from CuII ions and the dtb ligands. The pH values have a crucial influence on the formation of 1 and 2. In addition, the electrochemical and luminescent properties of 1 and 2 as well as magnetic properties of 1 were investigated.
