Knippen, Katharina; Bredenkoetter, Bjoern; Kanschat, Lisa; Kraft, Maryana; Vermeyen, Tom; Herrebout, Wouter; Sugimoto, Kunihisa; Bultinck, Patrick; Volkmer, Dirk published an article in 2020, the title of the article was CFA-18: a homochiral metal-organic framework (MOF) constructed from rigid enantiopure bistriazolate linker molecules.COA of Formula: C2H4ClNO And the article contains the following content:
In this work, authors introduce the first enantiopure bistriazolate-based metal-organic framework, CFA-18 (Coordination Framework Augsburg-18), built from the R-enantiomer of 7,7,7′,7′-tetramethyl-6,6′,7,7′-tetrahydro-3H,3’H-5,5′-spirobi[indeno[5,6-d]-[1,2,3]triazole] (H2-spirta). The enantiopurity and absolute configuration of the new linker were confirmed by several chiroselective methods. Reacting H2-spirta in hot N,N-dimethylformamide (DMF) with manganese(II) chloride gave CFA-18 as colorless crystals. The crystal structure with the composition [Mn2Cl2(spirta)(DMF)2] was solved using synchrotron single-crystal x-ray diffraction. CFA-18 shows a framework topol. that is closely related to previously reported metal-azolate framework (MAF) structures in which the octahedrally coordinated manganese(II) ions are triazolate moieties, and the chloride anions form crosslinked one-dimensional helical chains, giving rise to hexagonal channels. In contrast to MAFs crystallizing in the centrosym. space group R3, the handedness of the helixes found in CFA-18 is strictly uniform, leading to a homochiral framework that crystallizes in the trigonal crystal system within the chiral space group P3121 (number 152). The experimental process involved the reaction of 2-Chloroacetamide(cas: 79-07-2).COA of Formula: C2H4ClNO
