“…Furthermore, the ν(C=N) ring vibration modes for the uncoordinated N-donor ligands (bipy: ν(C=N) = 1587 cm À 1 ; bpe: ν(C=N) = 1594 cm À 1 ; bpa: ν(C=N) = 1593 cm À 1 ) were not observed.

“…[21][22][23][24][25] To date, only a limited number of examples are known for CPs and MOFs constituted from group 13 metal halides together with N-donor ligands. [26][27][28][29][30][31][32][33][34][35][36][37][38] The vast majority is constructed from d-block elements as inorganic building blocks and carboxylates as organic linkers. Group 13 metal trihalides act as strong Lewis acids, forming stable donor acceptor complexes in combination with N-donor ligands.…”

Dedicated to Prof. Dr. Christoph Janiak on the Occasion of his 60th Birthday Four indium-based, 2D coordination polymers (CP) were synthesized utilizing InCl 3 and InI 3 and the bidentate ligands 4,4'-bipyridine (bipy), 1,2-di(4-pyridyl)ethylene (bpe) and 1,2di(4-pyridyl)ethane (bpa). The isoreticular networks 2 1 [In 2 Cl 6 (bipy)] (1) and 2 1 [In 2 Cl 6 (bpe)] (2) are constituted by chloride-and ligand-bridged octahedra with a honeycomb like (6,3)-net topology (hcb topology). In contrast, 2 1 [(In 4 Cl 12 )(bpa) 3 ] (3) consists of {In 4 Cl 12 N 6 } units, with each indium atom being coordinated by chloride anions and bpa ligands in an octahedral fashion. Bpa ligands connect indium atoms in two dimensions, forming a semi-regular uninodal 3-c net with the point symbol (4,8 2 ), as present in the fes topology. In 2 1 [(InI 3 ) 2 (bpa) 3 ] (4), indium is coordinated by three iodide and three bpa ligands in a meridional fashion. In contrast to 2 1 [In 2 Cl 6 (bipy)] (1) and 2 1 [In 2 Cl 6 (bpe)] ( 2), the indium-centered octahedra are linked by the bidentate linker only, but also a honeycomb-like, zigzag-shaped (6,3)-net with a hcb topology is formed. The CPs were investigated by SCXRD, PXRD, IRspectroscopy, and with DTA/TG regarding their thermal properties. 2 1 [(In 4 Cl 12 )(bpa) 3 ] (3) and 21 [(InI 3 ) 2 (bpa) 3 ] (4), which were synthesized under solvothermal conditions utilizing the dipyridyle ligands 4,4'-bipyridine (bipy), 1,2-di(4-pyridyl)ethylene (bpe) and 1,2-di(4-pyridyl)ethane (bpa).

“…A variety of studies have demonstrated the coordination nanostructures by altering organic ligands, such as carboxylate, 3,5,12,18 hydroxyl, 14,20,21 pyridine, 9,22-25 and triazine. [26][27][28][29][30] The triazine derivatives are important in a range of areas as ligands for supramolecular self-assembly of more complex mixed layers, hence it may be interesting to study the coordination properties of the triazine derivatives. In this article, we fabricated different coordination nanostructures by 4,4 0 ,4 00 -(1,3,5-triazine-2,4,6-triyl) tribenzoic acid (TATB) molecules coordinating with Cu 2+ or Fe 3+ ion with different concentrations on highly oriented pyrolytic graphite (HOPG) surface.…”

Eight cationic, two-dimensional metal-organic frameworks (MOFs) were synthesized in reactions of the group 13 metal halides AlBr 3 , AlI 3 , GaBr 3 , InBr 3 and InI 3 with the dipyridyl ligands 1,2-di(4-pyridyl)ethylene (bpe), 1,2-di(4pyridyl)ethane (bpa) and 4,4'-bipyridine (bipy). Seven of them follow the general formula 2 ∞ [MX 2 (L) 2 ]A, M=Al, In, X=Br, I, A À =[MX 4 ] À , I À , I 3 À , L = bipy, bpa, bpe. Thereby, the porosity of the cationic frameworks can be utilized to take up the heavy molecule iodine in gas-phase chemisorption vital for the capture of iodine radioisotopes. This is achieved by switching between I À and the polyiodide I 3 À in the cavities at room temperature, including single-crystal-to-single-crystal transformation. The MOFs are 2D networks that exhibit (4,4)-topology in general or (6,3)-topology for 2 ∞ [(GaBr 2 ) 2 (bpa) 5 ][GaBr 4 ] 2 •bpa. The two-dimensional networks can either be arranged to an inclined interpenetration of the cationic two-dimensional networks, or to stacked networks without interpenetration. Interpenetration is accompanied by polycatenation. Due to the cationic character, the MOFs require the counter ions [MX 4 ] À , I À or I 3 À counter ions in their pores. Whereas the [MX 4 ] À , ions are immobile, iodide allows for chemisorption. Furthermore, eight additional coordination polymers and complexes were identified and isolated that elaborate the reaction space of the herein reported syntheses.
