Let¡¯s face it, organic chemistry can seem difficult to learn, COA of Formula: C10H16O, Especially from a beginner¡¯s point of view. Like 464-48-2, Name is (-)-Camphor, molecular formula is C2H5NO, belongs to amides-buliding-blocks compound. In a document, author is Kan, Wei-Qiu, introducing its new discovery.
Two Ag(I)-Containing Supramolecular Coordination Polymers Constructed from the Multidentate N-donor Ligand 1-((1H-1,2,4-triazol-1-yl)methyl)-3,5-bis(3-pyridyl)-1,2,4-triazole Based on Hydrogen-Bonding and pi-pi Interactions: Syntheses, Crystal Structures, Optical Band Gaps and Luminescent Properties
Two Ag(I)-based coordination polymers, namely [Ag-2(3,3 ‘-tmbpt)(o-Hbdc)(2)]center dot H2O (1) and [Ag-8(3,3 ‘-tmbpt)(4)(1,2,4-Hbtc)(4)(H2O)] (2) (3,3 ‘-tmbpt = 1-((1H-1,2,4-triazol-1-yl)methyl)-3,5-bis(3-pyridyl)-1,2,4-triazole, o-H(2)bdc = 1,2-benzenedicarboxylic acid and 1,2,4-H(3)btc = 1,2,4-benzenetricarboxylic acid), have been synthesized. Single-crystal X-ray diffraction analyses, elemental analyses, infrared spectra, powder X-ray diffraction analyses and thermogravimetric analyses have been carried out to characterize the structures of 1 and 2. Compound 1 shows a (3,4)-connected 2D layered structure with a Schlafli symbol of (4(2)center dot 6)(4(2)center dot 6(3)center dot 8). The intermolecular O-H center dot center dot center dot O hydrogen-bonding interactions extend the 2D layer into a 3D supramolecular architecture. Compound 2 exhibits a (3,3)-connected double-layered structure with a Schlafli symbol of (4 center dot 8 center dot 10)(2)(8(2)center dot 10)(2). The intermolecular C-H center dot center dot center dot O hydrogen-bonding interactions link the double-layers to form a 3D supramolecular architecture. Moreover, there are intramolecular and intermolecular pi-pi interactions in 1 and 2, which stabilize the whole 3D supramolecular architectures. The band gaps of 1 and 2 are 3.19 and 3.09 eV, respectively, indicating the potential of 1 and 2 as semiconductive materials with wide band gaps. Moreover, 1 and 2 emit intense blue-green light, which may be potential photoactive materials. Graphic Two Ag(I)-based 3D supramolecular coordination polymers constructed from a multidentate N-donor ligand and two aromatic polycarboxylate anions via hydrogen-bonding and pi-pi interactions have been synthesized and characterized. The band gaps and photoluminescent properties of the compounds have been studied.. [GRAPHICS] .
