The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 14348-75-5, Name is 2,7-Dibromo-9H-fluoren-9-one, SMILES is C3=C2C1=C(C=C(Br)C=C1)C(C2=CC(=C3)Br)=O, in an article , author is Qaseer, Hanan A., once mentioned of 14348-75-5, SDS of cas: 14348-75-5.
The solid-state structure of 5,6,7,8-tetrahydro-1,4-di(2′-pyridyl)phthalazine (6-dppn) was characterized by X-ray diffraction and a crystallographic study was then conducted. It was found that 6-dppn exists in the trans/trans conformation. This ligand crystallizes in P2(1)/c(14) space group with unit cell parameters of a = 9.698(2) angstrom, b = 9.999(4) angstrom, c = 10.7268(3) angstrom, beta = 92.890(6)degrees, Z = 8 and V = 2958.2(14) angstrom(3). The non-covalent interactions involved in the structure of 6-dppn were investigated and presented in terms of supramolecular chemistry and crystal engineering.
