Chemistry is traditionally divided into organic and inorganic chemistry. COA of Formula: C9H6ClN, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 19493-44-8
A series of nitrogen ligand (L)/copper complexes of the type [CuIL]+, [CuIIL(X)]+ and [CuIL2]+ (X= Cl-, BF-4, acac-, CH3COO- and SO3CF-3) was studied in the gas phase by electrospray ionization mass spectrometry. The following ligands (L) were employed: 1,12-diazaperylene (dap), 1,1′(-bisisoquinoline (bis), 2,2′(-bipyridine (bpy), 1,10-phenanthroline (phen), 2,11-disubstituted 1,12-diazaperylenes (dap), 3,3′(-disubstituted 1,1′- (bisisoquinoline (bis), 5,8-dimethoxy-substituted diazaperylene (meodap), 6,6′- (dimethoxy-substituted bisisoquinoline (meobis) and 2,9-dimethyl-1,10-phenanthroline (dmphen). Collision-induced decomposition measurements were applied to evaluate the relative stabilities of the different copper complexes. The influence of the spatial arrangement of the ligands, of the type of substituents and of the counter ion of the copper salts employed for the complexation was examined. Correlations were found between the binding constants of the [ML2]+ complexes in solution and the relative stabilities of the analogous complexes in the gas phase. Furthermore, complexation with the ligands 2,11-dialkylated 1,12-diazaperylenes [alkyl = ethyl (dedap) and isopropyl (dipdap)] was studied in the solvents CH3OH and CH3CN.
