The Isolation and Characterization of Molecular Complexes Produced from the Reaction of Nitrophenols with Divalent Metal Oxinates
نویسندگان
چکیده
The reaction of nitrophenols (picric acid, 2,6-dinitrophenol, and 2,4-dinitrophenol) with divalent metal oxinate (metal = Cu, Co, Ni, Mn, and Zn) produced a type of molecular complex, which comprises two molecules of the metal oxinate and one molecule of the nitrophenol. In the case of the Mg complex the ratio is 1:1. A definite charge-transfer band is detected for the Co(II) complex. A hydrogen bonding system 0I . . .H+.. .02 is suggested. This includes the proton of the nitrophenol and two oxygen atoms; each is related to a coordinated oxinate of two different metal oxinate molecules. Analytical and spectral evidence are in accordance with the tentatively suggested formulations.
